Answer: 9 feet.
Step-by-step explanation:
Let the radius of the sphere = x feet
Therefore, the volume of the sphere = \(\frac{4}{3} \pi x^3\)
But, According to the question,
The volume of the sphere = \(972\pi \text{ cubic feet }\)
⇒ \(\frac{4}{3} \pi x^3 = 972\pi\)
⇒ \(x^3 = 972\times \frac{3}{4}\)
⇒ \(x^3 = \frac{2916}{4}\)
⇒ \(x^3 = 729\)
⇒ \(x =9\)
Thus, the radius of the sphere = 9 feet
