Question

Find the volume of a sphere with a diameter of 15 cm

Answer 1

V= 562.5 pi cm^3 or approximately 1766.25 cm^3

Explanation:

If the diameter is 15, the radius is d/2 = 15/2 = 7.5

The volume of a sphere is

V = 4/3 pi r^3

V = 4/3 ( pi ) (7.5) ^3

V= 562.5 pi

If we use the approximation of 3.14 for pi

V = 1766.25 cm^3
