To find the surface area of a sphere, you can use the formula: A = 4πr^2, where r is the radius of the sphere. Since the diameter of the basketball is 9.2 inches, the radius would be half of that, which is 4.6 inches.
Plugging the radius into the formula, we get: A = 4(3.14)(4.6)^2 = 4(3.14)(21.16) = 265.77 inches squared.
Therefore, the surface area of the basketball is approximately 265.77 inches squared.
