Chapter IICharacteristics of cylinder, Cone, and sphere, and determining the

size

A. Cylinder1. Elements of cylinder

a. Base side of cylinderb. Center of circlec. Radius of circled. Diameter of circlee. Height of cylinderf. Cover of cylinder.

2. The large cylinderThe large of cylinder = large of stand side+ large of top side+ large of the base side

= large of stand side + 2 large of base side

3. Volume of cylinderVolume of cylinder can be mentioned as the following:

V = A × tV = (π r2 ) × t

B. Cone1. Elements of cone

a. Bas side of coneb. Center pointc. Radius of base side of coned. Diameter of base side of cone.e. Height of conef. Chord base side of coneg. Cover of cone

2. The large of sides

The large of cone’s sideL= πrs + πr2 With r = radius of cone

s = the length of drawing line

3. Volume of cone

Formula of volume of cone :

With r : radius and t : height of cone

C. Sphere1. Elements of sphere

a. Point O is central pointb. Radius of spherec. Diameter of sphered. Cover of spheree. Chord of spheref. Drawing line of sphere

2. The large of sphere’s cover

Large:L = 4 r2

With r : radius of sphere

3. Volume of sphere

Formula for the volume of sphere:V = 3∕4 π r3

With π = 3,14
