To find the surface area of a sphere, you can use the formula:
Surface Area = 4πr^2
The diameter of the basketball is given as 9.2 inches, so the radius would be half of that, which is 4.6 inches.
Now plug in the values into the formula:
Surface Area = 4π(4.6)^2
Surface Area = 4π(21.16)
Surface Area ≈ 84.64 inches squared
Therefore, the surface area of the basketball is approximately 84.64 in.2.
