WebJan 17, 2024 · The surface area of a sphere is given by \ (A = 4\pi {r^2},\) where \ (r\) is the radius of the sphere. In the formula for the surface area of a sphere, \ (4\) and \ (\pi \) are constants. The surface area of a sphere directly depends … WebJul 4, 2015 · Here is one way to solve the problem. The formula for the volume of a sphere is. V = 4 3 πr3. We can solve this for r. 3V = 4πr3 or 4πr3 = 3V. r3 = 3V 4π. r3 = 3× 288 in3 4π = 216 π in3 = 68.7549 in3. r = 3√68.7549 in3 = 4.0967 in. Now we can insert this value of r into the formula for the area of a sphere.
