Title: Pizza Math | Description: A simple guide to using math to get more for your money when buying pizza.
We've all been there: staring at a pizza menu, wondering if the single large pizza is a better value than two mediums. Our intuition often tells us that two pizzas are always a better deal, but the math tells a different story. The true value of a pizza isn't in its diameter, but in its **area**.
The area of a pizza is calculated using the formula for the area of a circle: $A = \pi r^2$, where $r$ is the radius. Because the radius is half the diameter, and the area depends on the **square** of the radius, a small increase in diameter results in a much larger increase in total pizza area.
For example, a 16-inch pizza has an area of roughly $201$ square inches. Two 10-inch pizzas, while they add up to 20 inches in diameter, only have a combined area of about $157$ square inches ($2 \times (\pi \times 5^2)$). This means the single large pizza gives you significantly more food for your money.
This simple calculator takes the guesswork out of the equation. By comparing the cost per square inch (or centimeter), you can be sure you're getting the most delicious deal possible.
