The curved surface area of a sphere measures 64π cm². What is the radius of the sphere?

Explanation

The curved surface area (surface area) of a sphere is given by the formula 4πr². Setting 4πr² = 64π, we divide both sides by 4π to get r² = 16. Taking the square root, r = 4 cm. Therefore, the radius of the sphere is 4 centimeters.
