Sean used candle molds, as shown, to make candles that were perfect cylinders and spheres:

A cylindrical mold is shown, the radius of the top circular section of the cylinder is labeled 3 inches and the height of the cylinder is labeled as 6 inches. On the right side of this mold is a spherical mold. The radius of this spherical mold is labeled as 3 inches.

What is the approximate difference in the amount of wax needed to make a candle from each of these molds? Use π = 3.14.
