Question

Work out the volume of this sphere.
give your answer to 1 decimal place

Answer 1

`Volume = 1436.3cm^3`

Explanation:

Given

`Radius = 7cm`

Required

Determine the volume

This is calculated as:

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

Substitute 7 for r

`Volume = (4)/(3)\pi * 343`

Substitute 22/7 for
`\pi`

`Volume = (4)/(3) * (22)/(7) * 343\\`

`Volume = (4)/(3) * (22)/(1) * 49`

`Volume = (4312)/(3)`

`Volume = 1436.3333`

`Volume = 1436.3cm^3` --- approximated
