The surface area of a spherical basketball is 400pi square inches. What is the radius of the lampshade? The formula for surface area of a sphere is V = 4x=pi r^2.

Answer 1

Given that the surface area of the spherical basketball is 400pi square inches, we can set up the equation:

400pi = 4pi r^2

Dividing both sides by 4pi gives us:

100 = r^2

Taking the square root of both sides gives us:

r = 10

Therefore, the radius of the lampshade is 10 inches.
