To find the surface area of a sphere, we use the formula:
Surface Area = 4πr²
Given that the diameter of the basketball is 9.2 inches, we can find the radius by dividing the diameter by 2:
Radius = Diameter/2 = 9.2/2 = 4.6 inches
Substituting the radius into the formula:
Surface Area = 4π(4.6)²
Surface Area = 4π(21.16)
Surface Area ≈ 84.64 inches squared
Therefore, the correct answer is: 84.64 in.2
