I have a worksheet with word problems, which are not my forte. Anyways, the problem is stated exactly as follows: \"At Cakes R Us, it is possible to buy round cakes in different sizes. The smallest cake has a diameter of 8 inches and height of 4 inches and requires 3 cups of batter. Another similar round cake has a diameter of 13 inches. How much batter would this cake require?\"  By the way, this problem is not in my book. It's on a worksheet my teacher gave me. Thanks so much.  </SPAN>\n" );
