Question

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

Answer 1

hey user!

your answer is here..

given the diameter of the sphere is 12 ft.

therefore radius of the sphere = 12/2 = 6 ft


`volume \: of \: the \: sphere = (4)/(3) \pi {r}^(3) \\ = (4)/(3) \pi( {6}^(3) ) \\ \\ = (4)/(3) \pi(216) \\ \\ = 288\pi {ft}^(3) \\ \\ cheers...`

Answer 2

Diameter = 12 ft
Radius = 12 ÷ 2 = 6 ft


`\text {Volume = } (4)/(3) \pi r^3`


`\text {Volume = } (4)/(3) \pi (6)^3 = 288 \pi \text{ ft}^3`
