## Pizza day and Pizza Formula V=Pi(z*z)a

February 9th is national pizza day. Me, the math nerd Dirk, is waiting for this day all year because I finally can explain the famous Pizza-Formula, or more precisely:

V = Pi (z*z)a

This formula computes the volume of a pizza. Mathematically, a pizza is a cylinder for which we can compute its volume. All we need to know the pizza’s thickness — a, and the radius — z. When we multiply the constant pi = 3.141592… with the square of the radius, that is pi*z*z we arrive at the surface area of the pizza.

A = Pi (z*z)

Now, we are only one simple multiplication away from the entire volume of the pizza. For this last multiplication we need the thickness a and arrive out our famous pizza-volume formula:

V = Pi (z*z) a

This picture visualizes the formula, thickness a and radius z.
