The formula for the surface area of a sphere is A = 4πr^2, where r is the radius of the sphere.
The diameter of the basketball is 9.2 inches, so the radius is half of that, which is 9.2/2 = 4.6 inches.
Substituting this value into the formula, we have A = 4 * 3.14 * (4.6)^2.
Calculating this expression, we get A = 4 * 3.14 * 21.16 = 334.496.
Rounding to the nearest hundredth, the surface area of the basketball is approximately 334.5 square inches.
Use the formula for the surface area of a sphere to find the surface area of a basketball that has a diameter of 9.2 inches. Use 3.14 pi and round your answer to the nearest hundredth, if necessary. .
