Volume of a tennis ball with radius - Sphere - Mensuration problem solver

The radius of a tennis ball is 2.1 cm. Find its volume.

volume of a tennis ball with radius

radius = 2.1
V =  (4/3) * PI * r ^ 3
volume = (4/3) * PI * 2.1 ^ 3
volume = 11
So the volume is 11

Sphere :

A three dimensional object shaped like a ball. Every point on the surface has the same distance from the center.

Sphere Formulas :

C =  2 * PI * r

d =  r * 2

r =  d / 2

V =  (4/3) * PI * r ^ 3

SA =  4 * PI * r ^ 2


where,

d = diameter
C = circumference
r = radius
V = volume
SA = surface area
