Question

Please help me out please

Answer 1

Answer:

$\frac{500\pi }{3}$ 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 = $\sqrt{25}$ = 5, hence

V = $\frac{4}{3}$πr³

   = $\frac{4}{3}$π × 5³

   = $\frac{4}{3}$π × 125 =   $\frac{500\pi }{3}$ ft³

Answer 2

Answer:

(500π)÷3

Step-by-step explanation:

area=4πr^2 , volume=4(πr^3)÷3

area=100π ,so r=5
