How much air is needed to fill a basketball with a diameter of 9 inches use 3.14 as an approximation for pi round your answer to the nearest 10th
To find the volume of the basketball, we can use the formula for the volume of a sphere:
Volume = (4/3) * π * radius^3
Given that the diameter of the basketball is 9 inches, the radius is half of that, which is 4.5 inches or 4.5/12 = 0.375 feet.
Substituting the values into the formula:
Volume = (4/3) * 3.14 * (0.375)^3 ≈ 0.381 cubic feet
Therefore, approximately 0.4 cubic feet of air is needed to fill the basketball.
