To find the surface area of a sphere, we use the formula:
Surface Area = 4πr^2
First, we need to find the radius of the basketball. The diameter is given as 9.2 inches, so the radius is half of the diameter.
Radius = 9.2 inches / 2 = 4.6 inches
Now we can use the formula to find the surface area:
Surface Area = 4π(4.6)^2
= 4π(21.16)
≈ 265.77 in.2
Rounded to the nearest hundredth, the surface area of the basketball is 265.77 inches squared.
So the correct answer is:
265.77 in.2
265.77 inches squared
