Chapter 13.3, Problem 12P

1. A cake recipe will make a round cake that is 6 in. in diameter and 2 in. high. a. If you use the same recipe but pour the batter into a round cake pan that is 8 in. in diameter, how tall will the cake be? Explain.
2. Suppose you want to use the same cake recipe to make a rectangular cake. If you use a rectangular pan that is 8 in. wide and 10 in. long, and if you want the cake to be about 2 in. tall, then how much of the recipe should you make? (For example, should you make twice as much of the recipe, half as much, three-quaners as much, or some other amount?) Give an approximate, but practical,answer. Explain.
