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.
265.77
66.44 in
84.64 in
1,063.08 in
The surface area of a sphere formula is A = 4πr^2, where r is the radius of the sphere. The radius of the basketball is half of its diameter, so r = 9.2/2 = 4.6 inches.
Plugging this radius into the formula, we get:
A = 4(3.14)(4.6^2)
A = 4(3.14)(21.16)
A = 4(66.5824)
A = 266.33
Rounded to the nearest hundredth, the surface area of the basketball is 266.33 square inches. The closest option is 265.77, so that is the correct answer.
