To find the surface area of a sphere, we use the formula:
Surface Area = 4πr^2
Given that the basketball has a diameter of 9.2 inches, we can find the radius by dividing the diameter by 2:
r = 9.2/2 = 4.6 inches
Now we can plug this value of r into the formula to find the surface area:
Surface Area = 4π(4.6)^2
Surface Area = 4π(21.16)
Surface Area ≈ 84.64 in.²
Therefore, the correct answer is:
84.64 in.²
