Question

A sphere has a diameter of 12 ft. What is the volume of the sphere? Give the exact value in terms of .

aft

Answer 1

904.78 is the answer

volume = 4/3 π r cubed

Answer 2

288π

That is exact value in terms of pi.

Explanation:

So if the diameter is 12, the radius is 6.

The volume of a sphere is
`(4)/(3) \pi r^3`

Since r = 6, the volume is
`(4)/(3) * 216\pi`

Which is 288π
