The formula for the surface area of a sphere is:
A = 4πr^2
Given that the diameter of the basketball is 9.2 inches, we can find the radius by dividing the diameter by 2:
r = 9.2 / 2 = 4.6 inches
Now, we can substitute the value of the radius into the formula:
A = 4π(4.6)^2
A = 4π(21.16)
A = 84.64 π
Using the value of pi as 3.14, we can calculate the surface area:
A = 84.64 * 3.14
A ≈ 265.77 in²
So, the surface area of the basketball is approximately 265.77 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.(1 point)
