The surface area of a sphere is calculated using the formula: 4πr², where r is the radius of the sphere. Since the radius is half the diameter, the radius of the basketball is 5 inches.
Plugging in the radius into the formula:
4π(5)² = 4π(25) = 100π
Therefore, the surface area of a basketball with a diameter of 10 inches is 100π in².
