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

Respuesta :

Answer:

The radius is 9 ft

Explanation:

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