The surface area of a spherical basketball is 400 pi square inches .

What is the radius of the basketball?
The formula for surface area of a sphere is SA=4 pi

1 answer

r^2

Given that the surface area of the basketball is 400 pi square inches, we can plug this into the formula and solve for the radius:

400 pi = 4 pi r^2

Dividing both sides by 4 pi:

100 = r^2

Taking the square root of both sides to solve for r:

r = 10 inches

Therefore, the radius of the basketball is 10 inches.
