Question

A sphere has a radius of 12 inches. A second sphere has a radius of 9 inches. What is the difference of the volumes of the spheres?

The volume of the larger sphere is π
cubic inches greater than the volume of the smaller sphere.

Answer 1

Solution given;

for sphere

radius [r]:12inches

another

radius [R]:9inches

Now

difference in volume of sphere:

volume of sphere of having radius [r-R]

=
`(4)/(3) πr³`-
`(4)/(3) πR³`

=
`(4)/(3) π`(12³-9³)

= 1332π cubic inches

The volume of the larger sphere is ___1332__π cubic inches greater than the volume of the smaller sphere.
