The radius of a fully inflated soccer ball is 4.5 inches. after using the ball for a game, the match referee, jason, measured the ball’s radius and found it had decreased to 4.4 inches. ignoring the thickness of the materials the soccer ball is made from, find the volume of the ball before and after the match, and find the difference of the volumes before and after the match.
