Question

What is the radius of a sphere with the volume of 125/6pi

Answer 1

`(5)/(2) = r`

Explanation:

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

`(125)/(6) \pi = (4)/(3) \pi r^3`

`(125)/(6) = (4)/(3) r^3`

`(3)/(4) ((125)/(6) ) = (3)/(4) ((4)/(3) )r^3`

`(125)/(8) = r^3`

`\sqrt[3]{125}` ÷
`\sqrt[3]{8}` = r

`(5)/(2) = r`
