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 tenth.
The volume of a sphere can be found using the formula V = (4/3)πr^3, where r is the radius of the sphere. The radius of the basketball is half of its diameter, so it is 9 inches / 2 = 4.5 inches.
Using the formula and approximating π as 3.14, the volume of the basketball is V = (4/3) * 3.14 * (4.5 inches)^3 = 381.99 cubic inches.
Therefore, approximately 382 cubic inches of air is needed to fill the basketball.
