To find the surface area of a sphere, we use the formula:
Surface Area = 4πr^2
Given that the diameter of the basketball is 9.2 inches, we can find the radius by dividing the diameter by 2:
Radius = 9.2 inches / 2 = 4.6 inches
Now, we can substitute the radius into the formula:
Surface Area = 4 * 3.14 * (4.6 inches)^2
Surface Area = 4 * 3.14 * 21.16 inches^2
Surface Area = 84.64 inches^2
Therefore, the surface area of the basketball is approximately 84.64 in.².
