The formula for the surface area of a sphere is given by:
Surface Area = 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:
r = 9.2 / 2 = 4.6 inches
Plugging this value into the formula, we get:
Surface Area = 4π(4.6)^2
Surface Area ≈ 4π(21.16)
Surface Area ≈ 4(3.14)(21.16)
Surface Area ≈ 84.64π
Using 3.14 as an approximation for π, we can calculate the actual value:
Surface Area ≈ 84.64(3.14)
Surface Area ≈ 265.8016
Rounding to the nearest hundredth, the surface area of the basketball is approximately 265.80 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
