The 10" pizza costs $1.13 per person (), the 13" pizza costs $1.25 per person (), so to minimize your cost, you serve the smaller pizzas. Of course, any of your guests who are mathematicians will recognize you as a cheapskate because the portions of the smaller pizza are about 2.5 square inches smaller than the portions of the larger pizza.

As long as we are talking about pizzas, I might as well share the Great Pizza Theorem.

Hence, the volume of a pizza with radius z and thickness a would be .

But . Therefore, the volume of pizza is pizza!
