To find the surface area of a sphere, you can use the formula:
Surface Area = 4πr^2
Given that the diameter of the basketball is 9.2 inches, we can first find the radius (r) by dividing the diameter by 2:
r = 9.2 inches / 2 = 4.6 inches
Now we can substitute the value of the radius into the formula:
Surface Area = 4π(4.6 inches)^2
Surface Area = 4π(21.16 inches^2)
Surface Area ≈ 266.78 inches^2
Rounding to the nearest hundredth, the surface area of the basketball is approximately 266.78 inches^2.
Therefore, the correct answer is:
265.77 in.2
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)
