Question

What is the volume (in cubic units) of a sphere with a radius of 21 units? Assume that =3.14 and round your answer to the nearest hundredth when necessary.

Answer 1

Answer:
`V=38772.72\ units^3`

Explanation:

Given

radius of sphere
`r=21\ units`

Volume of sphere can be calculated by this formula

`V=(4\pi )/(3)r^2`

`V=(4\pi )/(3)* (21)^3`

`V=(4\pi )/(3)* 9261`

`V=38772.72\ units^3`
