Formula
Which colour has the larger area?
Area of a circle is A
A = π r²
π = 3.14
r is radius
The red areas can be seen as four half circles which can make two circles
Formula
Which colour has the larger area?
Area of a circle isπ r²π = 3.14r is radius
r
The red areas can be seen as four half circles which can make two circles
Formula
Which colour has the larger area?
Area of a circle isπ r²π = 3.14r is radius
r
3.14 x (r x r) or the radius multiplied by the radius then multiply by 3.14
Formula
Which colour has the larger area?
Area of a circle isπ r²π = 3.14r is radius
r
3.14 x (r x r) or the radius multiplied by the radius then multiply by 3.14

Formula
Which colour has the larger area?
Area of a circle isπ r²π = 3.14r is radius
r
3.14 x (3 x 3) or 3 multiplied by 3 = 9 then multiply by 3.14 =
Formula
Which colour has the larger area?
Area of a circle isπ r²π = 3.14r is radius
r
3.14 x (3 x 3) or 3 multiplied by 3 = 9 then multiply by 3.14 = 28.26
Formula
Which colour has the larger area?
Area of a circle isπ r²π = 3.14r is radius

3.14 x (r x r) or the radius multiplied by the radius then multiply by 3.14
Formula
Which colour has the larger area?
Area of a circle isπ r²π = 3.14r is radius
r
3.14 x (2 x 2) or 2 multiplied by 2 then multiply by 3.14 =
Formula
Which colour has the larger area?
Area of a circle isπ r²π = 3.14r is radius
r
3.14 x (2 x 2) or 2 multiplied by 2 then multiply by 3.14 =12.56
Formula
Area (square) = 9 x 9 = 81;
Area (red) = 28.26 + 12.56 = 40.82;
Area (yellow) = 81 - 40.82 = 40.18.
Thus, Area (red) > Area (yellow).
