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?

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.
