answer.
The radius of the sphere is
feet.

Answer 1

Radius of sphere = 3 feet

Explanation:

The volume of sphere is 36 π ft³.

We need to find the radius of sphere.

The formula used is:
`Volume\:of\:sphere=(4)/(3)\pi r^3`

Putting value of volume and finding radius

`Volume\:of\:sphere=(4)/(3)\pi r^3\\36\pi =(4)/(3)\pi r^3\\r^3=36 \pi * (3)/(4\pi) \\r^3=9 * 3\\r^3=27\\Taking\:cube\;root\:on \:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{27}\\r=3`

So, Radius of sphere = 3 feet
