Question

the formula to find the volume of a sphere is v=4/3 π3^ , where r is the radius of the sphere. what is the formula in terms or r

Answer 1

r = ∛(
`(3V)/(4\pi )`)

Explanation:

You need to rearrange the equation to make r the subject of the formula:

v =
`(4)/(3)`πr³

`(3V)/(4)` = πr³

`(3V)/(4\pi )` = r³

∛(
`(3V)/(4\pi )`) = r

Answer 2

V = 4/3πr^3

3V = 4πr^3

`\sqrt[3]{3/4piV}` = r
