Marcus has been working on a large rubber band ball. When Marcus first measured the ball it had a diameter of 5 inches. Over the course of one year Marcus continued to add more rubber bands to the ball. After one year Marcus measured the rubber band ball, and it had a diameter of 15 inches. How much volume was added on to the rubber band ball? Round your answer to the nearest tenth.

Given this information, which expression must represent the value of b?
