Question

The volume of a sphere is 972π ft³. What is the radius of the sphere? enter your answer in the box.

Answer 1

The radius is 9 ft

Step-by-step explanation:

`V=(4)/(3) \pi r^3\\\\972\pi =(4)/(3) \pi r^3\\3(972\pi) =((4)/(3) \pi r^3)3\\2916\pi =4\pi r^3\\(2916\pi)/(4\pi ) =(4\pi r^3\\)/(4\pi ) \\729=r^3\\\sqrt[3]{729} =r\\9=r`
