Answer:

[tex]\frac{500\pi }{3}[/tex] ft³

Step-by-step explanation:

The surface area of a sphere = 4πr², hence

4πr² = 100π ( divide both sides by 4π )

r² = 25 ( take the square root of both sides )

r = [tex]\sqrt{25}[/tex] = 5, hence

V = [tex]\frac{4}{3}[/tex]πr³

   = [tex]\frac{4}{3}[/tex]π × 5³

   = [tex]\frac{4}{3}[/tex]π × 125 =   [tex]\frac{500\pi }{3}[/tex] ft³
