The formula for the surface area of a sphere is given by:
SA = 4πr^2
Since we are given the diameter of the basketball, we need to divide it by 2 to get the radius.
Radius = 9.2 inches / 2 = 4.6 inches
Now we can substitute this radius into the formula and calculate the surface area:
SA = 4π(4.6)^2
SA = 4π(21.16)
SA = 84.64π
Now we can use the value of π given (3.14) to approximate the answer:
SA ≈ 84.64 * 3.14
SA ≈ 265.54
Rounding to the nearest hundredth, the surface area of the basketball is approximately 265.54 square inches.
Therefore, the correct answer is not provided in possible options.
