Mr. P's favorite pizza place is MOD Pizza, which serves thin crust and lets you choose any toppings that you want for one price.
When Mr. and Mrs. P go to MOD Pizza, Mr. P orders an eleven inch radius pizza and Mrs. P orders the six inch pizza.
They decide to share the pizzas equally, but Mrs. P eats all of her pizza. What fractional part of Mr. P's pizza should she get
so that they each have the same number of square inches of pizza?
