Question

What is the volume of a sphere when r = 9 ft

Answer 1

`V=\frac43 \pi r^3\\ r=9m\\ \\ V=\frac43 \pi 9^3=\frac43 \cdot 729\pi=972\pi`

Answer 2

volume of a sphere is calculated using a formula:

`(4)/(3) \pi * r^(3)`

so in this case:


`(4)/(3) \pi * 9^(3)`

and taht is:


`(4)/(3) \pi *729`

`= 972 \pi`
