It all comes down to the the area of a circle - that equation you may have heard when you were young where the area = pi-r-squared (r being the radius). If we plug in some numbers you may notice something interesting. For example, since we measure pizza in inches in North America, the area of an 8” pizza is roughly 50 square inches. We simply take the radius of the pizza which is half of the diameter (so 4” in this case), put it in the equation and voila. But, if we do the same thing for a 16” pizza, which has a diameter that is two times bigger, we find that even though your intuition may say it’s twice as big, it actually has an area of over 200 square inches - which is 4 times MORE pizza. This is because the area of a circle increases with the square of the radius. And yet, most of the time the difference in price between an 8” pizza and a 16” pizza is not even two times more expensive, let alone 4 times more expensive! In fact, NPR did a survey of over 74,000 pizza prices across America, and created an interactive graph to show exactly how the price of pizza changes with size, and how much more pizza you get when you order a large. For example, an 20-inch pizza has more area than two 14-inch pizzas, or six 8 inch pizzas, yet it’s almost $9 cheaper on average than getting two 14 inch pizzas, and over $30 cheaper on average than getting six 8 inch pizzas. And this is the pizza equation: the bigger the diameter of the pizza, the more bang for your buck! But why is pizza so tasty in the first place?
