How do you calculate the price per square inch of pizza?

Answer 1

To calculate the price per square inch of Pizza, you will need to know the area if the pizza in square inches, and the price of the pizza.

For example, let's say you have a 12 inch pizza that cost 5 dollars. Pizzas are generally measured in diameter, so the diameter of the pizza is 12 inches, and the radius is half of that, or 6 inches.

The formula for the area of a circle is (1/2)(pi)(radius)2, which, in this case, is (1/2)(pi)(6 in)2, or about 56.5 in2.

We now know the area and the price. The formula for price per square inch is what is sounds like: (price)/(area in in2). In this case, it is (5)/(56.5), or about .089 dollars.

So this pizza costs about 9 cents per square inch.
