# How much bigger is a 16 inch pizza than a 14 inch?

A 16-inch pizza is **31% larger** than a 14-inch pizza in terms of area.

The size of a pizza is determined by its diameter, which is the distance across the center of the pizza. A 16-inch pizza is two inches larger in diameter than a 14-inch pizza. However, the difference in size between the two pizzas is not just two inches, but rather the area of the 16-inch pizza is significantly larger than the area of the 14-inch pizza.

To calculate the area of a circle (and thus the area of a pizza), you use the formula A = Οr^2, where A is the area, Ο is pi (approximately 3.14), and r is the radius of the circle (which is half the diameter).

So, the area of a 14-inch pizza is approximately 153.94 square inches (A = Οr^2 = 3.14 x 7^2), while the area of a 16-inch pizza is approximately 201.06 square inches (A = Οr^2 = 3.14 x 8^2). Therefore, the 16-inch pizza has about 31% more area than the 14-inch pizza, which means it can serve significantly more people or provide more leftovers.
