To find the surface area of a sphere, you can use the formula:
Surface Area = 4πr^2
Given that the diameter of the basketball is 9.2 inches, the radius would be half of the diameter, which is 4.6 inches.
Plugging this value into the formula:
Surface Area = 4 * 3.14 * (4.6)^2
Calculating this expression:
Surface Area = 4 * 3.14 * 21.16
Surface Area = 265.76
Rounding this to the nearest hundredth, the surface area of the basketball is approximately 265.77 inches squared.
Therefore, the correct answer is:
265.77 in.2
265.77 inches squared
