Question

An order of 12 balls is being packed for shipment to New Jersey. Each ball is 9 inches in diameter and weighs 14 ounces. If the shipment charges are based on the volume of the balls, what is the volume of one of the balls?

Answer 1

Assuming that the balls are perfect sphere, then we can use the formula for the volume of the sphere to solve the volume of the ball. the volume of a spher is given by the formula:
V = (4/3) pi r^3
where pi = 3.1416
r is the radius

since D = 9 in
r = 4.5 in

V = ( 4/3 ) (3.1416) ( 4.5)^3
V = 381.7 cubic inches is the volume of one of the balls.
