The formula for the surface area of a sphere is given by:
Surface Area = 4πr^2
Given that the diameter of the basketball is 9.2 inches, the radius (r) would be half of the diameter, so r = 9.2/2 = 4.6 inches.
Plugging in the value of the radius into the formula, we get:
Surface Area = 4 * 3.14 * (4.6)^2
Simplifying the expression:
Surface Area = 4 * 3.14 * 21.16
Surface Area ≈ 265.75
Rounded to the nearest hundredth, the surface area of the basketball would be 265.77 in.2. Therefore, the correct option is:
265.77 in.2
