To find the surface area of a sphere, we use the formula:
Surface Area = 4πr^2
Since the diameter of the basketball is given as 9.2 inches, the radius (r) would be half of the diameter, which is 4.6 inches.
Plugging in the values into the formula, we get:
Surface Area = 4 * 3.14 * (4.6)^2
= 4 * 3.14 * 21.16
≈ 265.76 in.²
Therefore, the correct answer is:
265.77 in.²
