Preface
3.14159265358 has been used as a value for the last 2000 years. This
number actually represents polygon of Exhaustion Method of Archimedes (240 BC)
of Syracuse, Greece. This is the only one geometrical method available even now.
The concept of limitation principle is applied and thus this number is attributed to
the circle. In other words, 3.14159265358 of polygon is a borrowed number and
attributed/ thrust on circle as its value, as the other ways, to find the length of the
circumference of circle, has become impossible with the known concepts, principles,
statements, theorems, etc.
From 1660 onwards, 3.14159265358 has been derived by infinite series
also, starting with John Wallis of UK and James Gregory of Scotland. This number
was obtained by Madavan of Kerala, India, adopting the same concept of infinite
series even earlier i.e. 1450. The World of Mathematics has recognized very
recently, that Madavan is the first to invent infinite series for the derivation of
3.14159265358. John Wallis and James Gregory too invented the infinite series
independently though later in period (George Gheverghese Joseph of Manchester
University, UK).
C.L.F. Lindemann (1882), Von K. Weirstrass and David Hilbert have
called 3.14159265358 as a transcendental number. The basis for their proof was
Eulers formula ei + 1 = 0 (Leonhard Euler, Swiss Mathematician, 1707-1783).
With their proofs, squaring of circle has become, without any doubt, an
unsolved geometrical problem. Thus, the present thinking on is, 3.14159265358
is the value which is an approximation and squaring of circle is impossible with the
number.
At this juncture, the true and an exact value equal to 14 2
4 =
3.14644660942. was discovered by the grace of God in March, 1998 after a
struggle of 26 years (from 1972) adopting Gayatri method. Hence, this value is
called the Gayatri value as the Gayatri method has revealed the true value for the
first time to the World. It was only a suspected value then, and however, it was
ii
not discarded, by this author. He continued and confirmed 14 2
4 as the real
value with Siva method, Jesus method and later with many more methods only.
A dilemma has thus crept into the minds of the people, which number
3.14159265358 or 14 2
4 = 3.14644660942 is the real value. One
responsibility before this author was to clear this dilemma. And, therefore, a book
was written collecting the work done in the past 12 years and titled Pi of the Circle in
2010, and is available in the website www.rsjreddy.webnode.com
The second responsibility before this author was also, to search for any flaw
in the derivation of the present value of equal to 3.14159265358
As a result of continuous search for 16 years further deep, two errors have
been identified. And one paper has been published. One is, that, 3.14159265358
belongs to the polygon and not to the circle. The second error is, to call of the circle
as a transcendental number. They (Lindemann, Weirstrass and Hilbert) may be
right in calling 3.14159265358 and not . Why ? It has been shown in earlier
paragraph that Eulers formula is the basis in calling 3.14159265358 as a
transcendental number. In the formula ei
+ 1 = 0, refers to radians equal to 1800
and not constant 3.14. constant has no place for it in the above formula.
When 3.14 is involved in the Eulers formula, the formula becomes wrong. Is it
acceptable then to call constant as transcendental number even though this has no
right of its participation in the above formula ? However, it is acceptable still, if one
agrees that radians 1800 = constant 3.14 or radians 180
0 is identical to
constant 3.14 Mathematics may not accept this howler.
Thus, on two counts i.e., 3.14159265358 is a polygon number and calling it
as a transcendental number, based on radians 1800. The present work on
unfortunately, is confusing. These are the two simple errors to be rectified
immediately. Here, the NATURE has kindly entered and rectified the errors by
revealing Gayatri value. It is exact and is an algebraic number. Squaring of circle
is also done, by ITs grace.

In this book there are two unpublished papers also, one is to show the first
method the base of this work after 26 years of struggle (Gayatri method) and two is
is, not a transcendental number (Arthanaareeswara method).

How did this Zoology Lecturer get encircled
himself in 1972 in Mathematics ?
Some people are curious to know, how did this student of Zoology enter
and entrench himself in this field of mathematics. Here is a brief narration:
This author loves book reading very much. One day in 1972, while reading an
encyclopedia he saw square, triangle, trapezium and so on and found constant
for circle alone in r2 and 2 r and such constant was not there for other
constructions. He questioned himself, Why. Why led to Why not
without for circle too. He thought many days. One day he inscribed a
circle in a square and found the diameter of the inscribed circle and the side of
the superscribed square equal. He was surprised and felt happy that he got the
clue to make real, the question Why not without . He thought and thought,
did many things, searched, studied, enquired fellow mathematicians, did
physical experiments, on-and-off, for next 26 years.
Being a government college teacher, he was transferred in the mean
time, from Piler (1971-81) to Kadapa, to Nagari, to Anantapur and finally to
Chittoor (in December 1995). No answer to his question of 1972.
He was 26 when question came, waited another 26 years and lost self
confidence. He was like a man swimming on the surface of the ocean looking
down and striving hard to take hold of the wanted pin with its visible blurred
image lying on the bottom of the ocean. Man looks up when he is helpless.
This was what happened to him also. He went to the nearby temple of Mother
Goddess Durga (at Chittoor) in 1998 and prayed to HER. He gave a word to
the goddess. When he gets answer and succeed in finding formulas for the
v
area and circumference of circle without equal to 22/7, he will keep
himself away from receiving awards, royalties, positions and avoid
felicitation functions, meetings etc. on account of future discovery.
Surprisingly, one Mr. Ramesh Prasad a physics teacher, next neighbor to this
author when discussed with him this long pending problem after the promise
to the Goddess before giving a clue he asked this author how did he had been
doing. The answer to him was, as inscribed circle, it is smaller in size
compared to the larger superscribed square the concept of difference had
been a dominating point. With this answer, Mr. Prasad told this author to
look at the problem, at the concept of ratio also and not only the factor of
difference. This author received this idea of Mr. Prasad and that whole night
worked on the problem and prepared an article and was sent to the Indian
Institute of Technology, Kharghpur, Mathematics Department, next morning.
The department was impressed with the paper and cautioned this author, was
not 22/7 and it was 3.1415926 in its reply with encouraging comments.
There, the search did not stop. Second question came anew. The new
question made this author why should there be 22/7, 3.1416, 3.1415926 By
March, 1998, during the rejuvenated search Gayatri Method, Siva method
came successively after many many many failures. Next 16 years,
continuous search has been focused on confirming, the correctness of 14 2
4
= 3.14644660942 as value. This author thanks the reader for this attentive
reading.

Pi treatment for the constituent rectangles of the superscribed
square in the study of exact area of the inscribed circle and its
value of Pi (SV University Method*)
R.D. Sarva Jagannadha Reddy
Abstract: Pi value equal to 3.14159265358 is derived from the Exhaustion method of Archimedes (240 BC) of Syracuse, Greece. It is the only one geometrical method available even now. The second method to compute
3.14159265358 is the infinite series. These are available in larger numbers. The infinite series which are of different nature are so complex, they can be understood and used to obtain trillion of decimals to
3.14159265358 with the use of super computers only. One unfortunate thing about this value is, it is still an
approximate value. In the present study, the exact value is obtained. It is 14 2
4
= 3.14644660942 A
different approach is followed here by the blessings of the God. The areas of constituent rectangles of the
superscribed square, are estimated both arithmetically, and in terms of of the inscribed circle. And value thus derived from this study of correct relationship among superscribed square, inscribed circle and constituent
rectangles of the square, is exact.
Keywords: Circle, diagonal, diameter, area, radius, side, square
I. Introduction Square is an algebraic geometrical entity. It has four sides and two diagonals which are straight lines.
A circle can be inscribed in the square. The side of the square and the diameter of the inscribed circle are same.
This similarity between diameter and side, has made possible to find out the exact length of the circumference
and the exact extent of the area of the circle, when this interrelationship between circle and its superscribed
square, are understood in their right perspective. The difficulty is, the inscribed circle is a curvature, though, its
diameter/ radius is a straight line as in the case of side, diagonal of the square. When we say a different approach is adopted, it means, these are entirely new to the literature of mathematics. The universal acceptance
to the new principles observed in the following method is a tough job and takes time. However, as the
following reasoning ways are cent percent in accordance with the known principles, understanding of the idea is
easy.
To study the different dimensions, such as, circumference and area of circle, constant is inevitable. Similarly, to understand perimeter and area of the square, 4a and a2 are adopted and hence, no constant similar
to circle is necessary in square. In the present study, the area of the square is divided into five rectangles. The
areas of rectangles are calculated in two ways: they are: 1. Arithmetical way and 2. In terms of of the
inscribed circle. Finally, the arithmetical values are equated to formulas having , and the value of is derived ultimately, which is exact.
II. Procedure Draw a square and its two diagonals. Inscribe a circle in the square.
1. Square = ABCD, AB = Side = a
2. Diagonals = AC = BD = 2a 3. O Centre, EF = diameter = side = a 4. The circumference of the circle intersects two diagonals of four points: E, H, F and G. Draw a parallel line IJ to the sides DC, passing through G and F.
5. OG = OF = radius = a/2
6. Triangle GOF. GF = hypotenuse = OG 2 = a
22 =
2a
2 = GF

and
S. No. 14 this is equal to S.No. 16 26. As the area of the corner region is equal to any one of the 4 bottomed rectangles,
then it is = 24 a

(S.No. 20 & 21)
27. Then the sum of the areas of 4 bottomed rectangles

= 24 a
28. Finally, Area of the uppermost rectangle DIJC
= Square area 4 bottomed rectangles
= 2 2 2a 4 a 3 a
29. CJ length = 3 a Side = AB = IJ = a
30. Area of the upper most rectangle DIJC

Uppermost rectangle DIJC = 23 a
4 bottomed rectangles = 24 a Area of the ABCD square Uppermost rectangle + 4 bottomed rectangles
= 2 2 23 a 4 a a Area of the inscribed circle = Uppermost rectangle DIJC + 3 bottomed rectangles

This is the end of the process of proof.

III. Conclusion It is well known, that a2 is the formula to find out area of a square or a rectangle. In this paper besides
a2, formulae, in terms of , of the inscribed circle in a square, are obtained, and equated to the classical arithmetical values of a2. One has to admire the Nature, that, a circles area can also be represented exactly equal, by the areas of rectangles, thus, the arithmetical values of these rectangles, are equated to that of a circle,
which thus give rise to new value 14 2

Archimedes (240 BC) of Syracuse, Greece, called the area arbelos that is inside the larger semi circle,
but outside the two smaller semi circles of different diameters. By its shape it is also called as a shoemakers knife.
The Golden Ratio and the arbelos of Archimedes are different concepts. But in this paper by the grace
of God, it has become possible to see that these two concepts too have an interesting and unexpected inter
relationship between each other (one). Further, this relationship has an extended relationship also with the circle
(two). It is a well known fact that there exists simple and understable relationship between circle and square
(three). As circle, square are related, their combined interrelationship has been extended to value also (four). There is, thus, a divine chain of bond (of four interconnecting relations) exists, among square,
circle, Golden Ratio, arbelos and value. (Here value means a true/ real/ exact/ line-segment based value.
The stress here, on the adjectives to , has become necessary, because 3.14159265358 of Polygon is attributed or thrust on circle. In other words, this number to circle is a borrowed number from polygon and its
existence thus can not be seen in the radius of the circle, naturally. However, the new value 14 2
4
=
3.14644660942 (unlike with official value 3.14159265358) is inseparable with radius and is, here, humbly submitted to the World of Mathematics:
Area of the circle = 27r 2rr r
2 4
Circumference of the circle = 2r 2r
6r2
= 2r
In support of the above formulae, this paper also chooses and confirms that the real value is 14 2

II. Procedure
1. Draw a square ABCD. Draw two diagonals. Inscribe a circle with centre O and with radius 1
2,
equal to half of the side AB of the square, whose length is 1.
AB = Side = EN = diameter = 1
AC = BD = Diagonal = 2 2. E is the mid point of AD
AE = 1
2, AB = 1
Triangle EAB, EB = hypotenuse = 5

3. EN = Diameter = 1
EJ = HB = 5 1

= 0.61803398874
JN = EN EJ = 5 1

= 3 5
2
= 0.38196601126
4. Draw two semicircles on EN. And one semicircle with EJ as its diameter, and second semicircle with JN as its diameter.
5. So, the diameter of the EJ semicircle = Golden Ratio = 5 1
2
and
the diameter of the JN semicircle = 3 5
2
6. The area present (which is shaded) outside the two semicircles (of EJ and JN) and within the larger EN semi circle, is called arbelos of Archimedes.
7. Draw a perpendicular line on EN at J which meets circumference at K.
KJ = EJ JN (this is Altitude Theorem)

8. Draw a full circle with diameter KJ. It has already been established that this area of the full circle is equal to the area of the shaded region called arbelos.
9. To calculate the area of the arbelos we have the following formulas.
q d q4
and
2h

where h = perpendicular line KJ = 5 2 = diameter of the circle LKM

(when a circle is inscribed in a square, or when a square is created from the four equidistant tangents on a
circle, the length of the circumference of the inscribed circle can be demarcated in the perimeter of the
superscribed square. It is called rectification of the circumference of the circle).
Part III (Area of the arbelos)
Let us calculate now the area of the arbelos with the known two values, official value and new one called
Gayatri value.
15. With official value
0.236067977494
=
3.141592653580.23606797749
4 = 0.18540735595
(S. No. 10)
x 0.05901699437 = 3.14159265358 x 0.05901699437 = 0.18540735594
(S. No. 11)
16. With Gayatri value
0.236067977494
=
3.146446609420.23606797749
4 = 0.18569382184
(S.No. 10)
0.05901699437 = 3.14644660942 x 0.05901699437 = 0.18569382183 (S.No. 11)
17. Finally, we obtain two different values representing same area of the arbelos of Archimedes.
Official value gives: 0.18540735595 and
Gayatri value gives: 0.18569382184 Which one is the actual value for the area of the arbelos ? The answer can be found in Part IV.
Part IV
18. In the Figure 1 we have Golden Ratio, HB equal to 5 1
2
= 0.61803398874
19. Let us divide area of the arbelos of S.No. 17 with the Cube of Golden Ratio =
3
5 1
2
and
multiply it with 16
14 2 of the formula, derived in the S.No.14, which finally gives the area of the square
ABCD, equal to 1.
The value that gives the exact area of the square equal to 1 is confirmed as the real value. Here, the
Golden Ratio decides, the real value, by choosing the correct area of the arbelos of Archimedes of S.No. 17
20. Area of the arbelos obtained with official value (S.No. 17)

As the exact area of the superscirbed square is obtained, it is clear, therefore, that, the real value is 14 2

III. Conclusion It is well known that there exists a simple relationship between circle and square. In the present study,
it is clear such simple relation also exists between Golden Ratio and arbelos of Archimedes. This paper
combines above two kinds of relations and decides the real value, as 14 2

Abstract: - value 3.14159265358 is an approximate number. It is a transcendental number. This number
says firmly, that the squaring of a circle is impossible. New value was discovered in March 1998, and it is
14 2
4
= 3.14644660942.. It is an algebraic number. Squaring of a circle is done in this paper. With
this new value, exact area of the arbelos is calculated and squaring of arbelos is also done. Arbelos of
Archimedes chooses the real value.
Keywords: - Arbelos, area, circle, diameter, squaring, side
I. INTRODUCTION Circle and square are two important geometrical entities. Square is straight lined entity, and circle is a
curvature. Perimeter and area of a square can be calculated easily with a2 and 4a, where a is the side of the square. A circle can be inscribed in a square. The diameter d of the inscribed circle is equal to the side a of
the superscribed square. To find out the area and circumference of the circle, there are two formulae r2 and
2r, where r is radius and is a constant. constant is defined as the ratio of circumference and diameter of
its circle. So, to obtain the value for , one must necessarily know the exact length of the circumference of the circle. As the circumference of the circle is a curvature it has become a very tough job to know the exact value
of circumference. Hence, a regular polygon is inscribed in a circle. The sides of the inscribed polygon doubled
many times, until, the inscribed polygon reaches, such that, no gap can be seen between the perimeter of the
polygon and the circumference of the circle. The value of polygon is taken as the value of circumference of
the circle. This value is 3.14159265358
In March 1998, it was discovered the exact value from Gayatri method. This new value is 14 2
4
=
3.14644660942.
In 1882, C.L.F. Lindemann and subsequently, Vow. K. Weirstrass and David Hilbert (1893) said that
3.14159265358 was a transcendental number. A transcendental number cannot square a circle. What is squaring of a circle ? One has to find a side of the square, geometrically, whose area is equal to the area of a
circle. Even then, mathematicians have been trying, for many centuries, for the squaring of circle. No body could succeed except S. Ramanjan of India. He did it for some decimals of 3.14159265358 His diagram is shown below.
Then the square on BX is very nearly equal to the area of the circle, the error being less than a tenth of an inch when the diameter is 40 miles long.

With the discovery of 14 2

= 3.14644660942 squaring of circle has become very easy and is done
here. Archiemedes (240 BC) of Syracuse, Greece, has given us a geometrical entity called arbelos. The shaded area
is called arbelos. It is present inside a larger semicircle but outside the two smaller semicircles having two
different diameters.
In this paper squaring of circle and squaring of arbelos are done and are as follows.
Squaring of inscribed circle
QD is the required side of square
Squaring of arbelos YB is the required side of square

Arbelos area x 25 16

= Area of the ABCD square, equal to 1.
As there are two values representing for the same area of the arbelos, let us verify, with the both the values, which is ultimately the correct one.
Arbelos area of official value 3.14159265358

= 0.99845732137 and
Arbelos area of new value 14 2

14 2 25 161
100 4 14 2
This process is done by understanding the actual and exact interrelationship among, 1. area of the ABCD
square, 2. area of the inscribed circle in ABCD square and, 3. area of the arbelos of Archimedes.
34. For questions why, what and how of each step, the known mathematical principles are insufficient, unfortunately.
So, as the exact area of ABCD square equal to 1 is obtained finally with new value. The new value equal to
14 2
4
is confirmed as the real value. This is the Final Judgment of arbelos of Archimedes.
III. CONCLUSION This study, proves, that squaring of a circle is not impossible, and no more an unsolved geometrical problem.
The belief in its (squaring of circle) impossibility is due to choosing the wrong number 3.14159265358 as
value. The new value 14 2
4
has done it. The arbelos of Archimedes has also chosen the real value in
association with the inscribed circle and the ABCD superscribed square.

Aberystwyth University Method for derivation of the exact value
R.D. Sarva Jagannadha Reddy Abstract - Polygons value 3.14159265358 of Exhaustion method has been in vogue as of the circle for the last 2000 years. An attempt is made in this paper to replace polygons approximate value with the exact value of circle with the help of Prof. C.R. Fletchers geometrical construction.
Keywords: Circle, diagonal, diameter, Fletcher, , polygon, radius, side, square
I. INTRODUCTION
The official value is 3.14159265358 It is considered as approximate value at its last decimal place, always. It implies that there is an exact value to be found in its place. a2, 4a, ab etc are the formulas of square and triangle which are derived based on their respective line-segments. Similarly, radius is a line-segment and a need is there to have a formula with radius alone and without . The following formulas are discovered (March, 1998) from Gayatri method and Siva method.
1. Area of Circle = 27r 2r

2. Circumference of Circle = 2r 2r6r 2 r

Draw a square ABCD. Draw two diagonals. O is the centre. Inscribe a circle with centre O and radius . Side of the square is 1. E, F, G and H are the midpoints of four sides. Join EG, FH, EF, FG, GH and HE. Draw four arcs with centers A, B, C and D and with radius . Now the circle-square composite system is divided into 32 segments of two different dimensions, called S1 segments and S2 segments. Number them from 1 to 32. There are 16 S1 and 16 S2 segments in the square and 16S1 and 8S2 segments in the circle.

From the diagram of Fletcher the area of the shaded segment cannot be calculated arithmetically. The diagram of the Siva method helps in calculating the area of the shaded segment. How ?
Shaded area of Fletcher is equal to two S2 segments 19 and 20 of Siva method.
This author, in his present study, has utilized radius/ diameter as usual, and a corner length, in addition, of the construction to find out the arithmetical value to the shaded area. A different approach is adopted here. What is that ? As a first step the shaded area is calculated using four factors. They are of Fig-2.

And, with the new value derived above, the area of the shaded region is equal to

So, this method creates a dispute now. Which value is right i.e. is 3.14159265358 or

The study of this method is extended further to decide which value is the real value ?
To decide which is real, a simple verification test is followed here. What is that ? We have a line

LK is part of the diagonal along with the corner length KC.
So, in the Second step, an attempt is made to obtain the LK length, from the area of the shaded region. How ? Let us take the reciprocal of the area of the shaded region;

Then, this value when divided by 32, we surprisingly get KL length. It may be questioned why one should divided that value. The answer is not simple. Certain aspects have to be believed, without raising questions like what, why and how at times.

=0.14644660942 and differs however with 0.14561851144 of official from 3rd decimal
onwards. If this argument is accepted, the present value 3.14159265358 is not approximate value from its last decimal place, but it is an approximate value from the 3rd decimal.
IV. CONCLUSION
From the beginning to the end of this method, various line-segments are involved. Professor Fletchers construction is analyzed arithmetically with the line-segments of the Siva method. This arithmetical
interpretation has resulted in the derivation of a new value, equal to 14 2

. The new value is exact,
algebraic number.

New Method of Computing value (Siva Method)
RD Sarva Jagannada Reddy
I. Introduction
equal to 3.1415926 is an approximation. It has ruled the world for 2240 years. There is a necessity to find out the exact value in the place of this approximate value. The following method givesthe total area of
the square, and also the total area of the inscribed circle. derived from this area is thus exact.
II. Construction procedure Draw a circle with center 0 and radius a/2. Diameter is a. Draw 4 equidistant tangents on the
circle. They intersect at A, B, C and D resulting in ABCD square. The side of the square is also equal to
diameter a. Draw two diagonals. E, F, G and H are the mid points of four sides. Join EG, FH, EF, FG, GH and HE. Draw four arcs with radius a/2 and with centres A, B, C and D. Now the circle square composite
system is divided into 32 segments and number them 1 to 32. 1 to 16 are of one dimension called S1 segments
and 17 to 32 are of different dimension called S2 segments.
III. Calculations: ABCD = Square; Side = a, EFGH = Circle, diameter = a, radius = a/2
Area of the S1 segment =26 2

V. Both the values appear correct when involved in the two formulae a) Official value = 3.1415926

Hence, another approach is followed here to decide real value.
VI. Involvement of line-segments are chosen to decide real value. A line-segment equal to the value of ( - 2) in S1 segments formula and second line-segment equal to the
value of (4 - ) in S2 segments formula are searched in the above construction.
a) Official : - 2 = 3.1415926 - 2 = 1.1415926. Proposed : - 2 = 14 2

Jesus Method to Compute the Circumference of A Circle and
Exact Value
RD Sarava Jagannada Reddy
I. Introduction The Holy Bible has said value is equal to 3. Mathematicians were not satisfied with the value. They thought over. Pythagorean theorem came in the mean time. A regular polygon with known perimeter was
inscribed in a circle and the sides doubled successively until the inscribed polygon touches the circumference,
leaving no gap between them. Hence this method is called Exhaustion method. The value of the perimeter of
the inscribed polygon is calculated applying Pythagorean theorem and is attributed to the circumference of the
circle. This method was interpreted, first time, on scientific lines by Archimedes of Syracuse, Greece. He has
said value is less than 3 1/7. Later mathematicians have refined the Exhaustion method and found many decimals. The value is
3.1415926 and this value has been made official. From 15
th century (Madhava (1450) of South India) onwards infinite series has been used for more
decimals to compute 3.1415926 of geometrical method. Notable people are Francois Viete (1579), Van
Ceulen (1596), John Wallis (1655), William Brouncker (1658) James Gregory (1660), G.W. Leibnitz
(1658), Isaac Newton (1666), Machin (1776), Euler (1748), S. Ramanujan (1914), Chudnovsky brothers
(1989). The latest infinite series for the computation of value is that of David Bailey, Peter Borwein and Simon Plouffe (1996) and is as follows:
0
1 4 2 1 1
16 8 1 8 4 8 5 8 6ii i i i i
Using above formula Yasumasa Kanada of Tokyo University, Japan, calculated trillions of decimals
to 3.1415926.. with the help of super computer. Mathematics is an exact science. We have compromised with an approximate value. Hence, many
have tried to find exact value. This author is one among the millions. What is ? It is the ratio of circumference of a circle to its diameter. However, in Exhaustion method, perimeter of the inscribed polygon is
divided by the diameter of the outside circle. Thus 3.1415926. violates the definition of . This is about the
value of . Next, about the nature of . C.L.F. Lindemann (1882) has said is a transcendental number based
on Eulers formula 1 0ie . In Mathematical Cranks, Underwood Dudley has said s only position in mathematics is its relation to infinite services (and) that has no relation to the circle. Lindemann proclaimed the squaring of the circle impossible, but Lindemanns proof is misleading for he uses numbers (which are approximate in themselves) in his proof.
Hence, pre-infinite series days of geometrical method is approached again to find out exact value
and squaring of circle. This author has struggled for 26 years (1972 to 1998) and calculated the exact value of
in March, 1998. The following method calculates the total length of circumference and thus the exact value has been derived from it.
Procedure: Draw a square. Draw two diagonals. Inscribe a circle. Side = a,
Diagonal = 2a , Diameter is also = a = d. 1) Straighten the square. Perimeter = 4a
Perimeter Sum of the lengths of two diagonals = 4 2 2a a = esp esp = end segment of the perimeter of the square.

2) Straighten similarly the circumference of the inscribed circle
3 diameters plus some length, is equal to the length of the circumference.
Let us say circumference = x.
Circumference 3 diameters = x 3a = esc esc = end segment of the circumference of the circle.
3) When the side of the square is equal to a, the radius of the inscribed circle is equal to a/2. So, the radius is 1/8
th of the perimeter of the square.
4) The above relation also exists between the end segment of the circumference of the circle and the end segment of the perimeter of the square.
Thus as radius 2
a
of the inscribed circle is to the perimeter of the square (4a), i.e., 1/8th
of it,
so also, is the end segment of the circumference of the circle, to the end segment of the perimeter
of the square.
So, the end segment of the circumference = 8

Supporting Evidences To the Exact Value from the Works Of Hippocrates Of Chios, Alfred S. Posamentier And Ingmar
Lehmann
R.D. Sarva Jagannadha Reddy 19-9-73/D3, Sri Jayalakshmi Colony, S.T.V. Nagar, Tirupati 517 501, A.P., India
Abstract: Till very recently we believed 3.1415926 was the final value of .And no body thought exact value would be seen in future. One drawback with 3.1415926is, that it is not derived from any line-segment of the circle. In fact, 3.1415926 is derived from the line-segment of the inscribed/ circumscribed polygon in and about circle, respectively. Surprisingly, when any line-segment of the circle is involved two things
happened: they are 1. Exact value is derived and 2 that exact value differs from 3.1415926 from its 3rd decimal onwards, being 3.1464466 Two geometrical constructions of Hippocrates of Chios, Greece (450 B.C.) and Prof. Alfred S. Posamentier of New York, USA, and Prof. Ingmar Lehmann of Berlin, Germany, are
the supporting evidences of the new value. They are detailed below. Keywords: value, lune, triangle, area of curved regions
I. Introduction In the days of Hippocrates, value 3 of the Holy Bible was followed in mathematical calculations.
He did not evince interest in knowing the correct value of . He wrote a book on Geometry. This was the first book on Geometry. This book became later, a guiding subject for Euclids Elements. He is very famous for his squaring of lunes. Prof. Alfred S. Posamentier and Prof. Ingmar Lehmann wrote a very fine
collaborative book on . They have chosen two regions and have proved both the regions, though appear very different in their shapes, still both of them are same in their areas. These areas are represented by a formula
2 12
r
. The symbol r is radius. , here must be, the universally accepted 3.1415926
Every subject in Science is based on one important point. It would be its soul. In Geometry, the soul is
a line-segment. The study of right relationship between two or more line-segments help us to find out areas,
circumference of a circle, perimeters of a triangle, polygon etc. For example, we have side in the square, base,
altitudein the triangle. The same concept is extended here, to show its inevitable importance in the study of
two regions of Professors of USA and Germany. The lengths of the concerned line-segments have been arrived
at and associated with 2 12
r
. 3.1415926 does not agree with the value of line-segments of two regions.
However, the new value 3.1464466 = 14 2
4
has agreed in to-to with the line-segments of the two regions
of the Professors. This author does believe this argument involving interpretation of 2 12
r
with the line-
segments, is acceptable to these great professors and the mathematics community. It is only a humble
submission to the World of Mathematics. Judgment is yours. If this argument in associating line-segment with
the formula looks specious or superficial, this author may beexcused.
II. Procedure The two methods are as follows:
1. Hippocrates' Method of Squaring Lunes And Computation of The Exact Value
Archimedes's procedure for finding approximate numerical values of (without, of course, referring
to as a number), by establishing narrower and narrower limits between which the value must lie, turned out to be the only practicable way of squaring the circle. But the Greeks also tried to square the circle exactly, that is
they tried to find a method, employing only straight edge and compasses, by which one might construct a square
equivalent to the given circle. All such attempts failed, though Hippocrates of Chios did succeed in squaring
lunes.
Hippocrates begins by noting that the areas of similar segments of circles are proportional to the
squares of the chords which subtend them

Consider a semi-circle ACB with diameter AB. Let us inscribe in this semi-circle an isosceles triangle
ACB, and then draw the circular arc AMB which touches the lines CA and CB at A and B respectively. The
segments ANC, CPB and AMB are similar. Their areas are therefore proportional to the squares of AC, CB and
AB respectively, and from Pythagoras's theorem the greater segment is equivalent to the sum of the other two.
Therefore the lune ACBMA is equivalent to the triangle ACB. It can therefore be squared.
The Circular arc AMB which touches the lines CA and CB at A and B
respectively can be drawn by taking E as the centre and radius equal to EA or EB.

With the guidance of the formulae of earlier methods of the author where a

1. Area of ANC = Area of CPB =

As the value 0.1464466 which is half of FC or HK is in agreement with the area value of A/B region
equal to 1.1464466 in decimal part, it is argued that new value equal to 1 14 24
= 3.1464466
is exactly correct.
The decimals 0.1415926 of the official value 3.1415926 does not tally beyond 3rd decimal with the half
the lengths of HK and FC, whose value is 0.1464466, thus, the official value is partially right. Whereas, FC
& HK are incompatible with the areas of A & B calculated using official value. Then, which is real, Sirs?
III. Conclusion 3.1415926 agrees partially (upto two decimals only) with the line-segments of curved geometrical
constructions. When these line-segments agree totally and play a significant role in these constructions a
different value, exact value 14 2

= 3.1464466 invariably appears. Hence,
14 2

is the true valueof

New Value: Its Derivation and Demarcation of an Area of
Circle Equal to 4
In A Square
R.D. Sarva Jagannadha Reddy
ABSTRACT: value is 3.14159265358 it is an approximation, and it implies the exact value is yet to be found. Here is a new method to find the most sought after exact value. 3.14159265358 is actually is the value of inscribed polygon in a circle. It is a transcendental number. When line-segments of circle are involved
in the derivation process then only the exact value can be found. 14 2
4
= 3.14644660942 thus obtained
is an algebraic number and hence squaring of circle is also done in the second part (method-3) of this paper.

I. INTRODUCTION
METHOD-1: Computation of tail-end of the length of the circumference over and above three
diameters of the Circle
The Holy Bible has said value is 3. Archimedes (240 BC) of Syracuse, Greece has said value is
less than 3 1/7. He has given us the upper limit of value. In 3 1/7, 3 represents three diameters and 1/7
represents the tail-end of the circumference of the circle (d = circumference)
In March, 1998, Gayatri method said the value as 14 2
4
= 3.14644660942 and its tail-end of the
length of the circumference of a circle over and above its 3 diameters as equal to 1
2 2 4 when the diameter is
equal to 1.
1/7 of Archimedes = 0.142857142857

2 2 4 of Gayatri method =

6.82842712474 = 0.14644660942
In the days of Archimedes there was no decimal system, because there was no zero. Archimedes is
correct in saying the tail-end length of the circumference is less than 1/7. How ? Gayatri method supports
Archimedes concept of less than 1/7 by giving 1
6.82842712474. The denominator part of the fraction, is
actually, less than 7 of 1/7. He is a great mathematician. This fraction 1
6.82842712474 has become possible
because of the introduction of zero in the numbers 1 to 9 and further consequential result of decimal system of
his later period. If he comes back alive, with his past memory remain intact, Archimedes would say, what he
had visualized in 240 BC has become real.
II. PROCEDURE Let us see how this tail-end value of circumference is obtained: Draw a circle with Centre O and
radius a/2. Draw four equidistant tangents on the circumference. They intersect at four prints called A, B, C
