A pool toy manufacturer makes a ball that has a 12-inch diameter. The company plans to make a new ball with a diameter that is 20% larger than the diameter of the original ball. By what percent will the volume of the new ball increase compared to the volume of the original ball?
- The radius is half the length of the diameter; therefore, a ball with a 12-inch diameter has a 6-inch radius.
- A 20% larger diameter ball has a diameter that is 14.4 inches.
- To find the volume of each ball, use the formula π.
- Compare the volume of the pool balls.
