The next time you hear someone complain about never being able to apply the math they learned in school in real life, remember this question.
You’d think the two smaller pies would have more pizza, but they don’t.
You just need some pi with your pizza.
Remember the formula: A = rcR2 (A = area; R = radius).
The area of the pizza’s circles is the same as half their diameters (5 and 3.5 inches, respectively) multiplied by itself (25 and 12.25) times 3.1416 (pi).
So a 10-inch pizza has about 78.5 square inches of cheesy goodness, while two 7-inch pizzas have only about 77 square inches.
