Wikipedia: Pizza
Pizza (Italian: [ˈpittsa], Neapolitan: [ˈpittsə]) is a dish of Italian origin consisting of a usually round, flattened base of leavened wheat-based dough topped with tomatoes, cheese, and often various other ingredients (such as anchovies, mushrooms, onions, olives, pineapple, meat, etc.), which is then baked at a high temperature, traditionally in a wood-fired oven.

I saw a cute mnemonic on a math web site the other day....they were talking about the volume of a somewhat-idealized cylindrical pizza of radius z and thickness (height) a:

Volume = pi暘暘戢

There is also a second pizza theorem. This one gives the VOLUME of a pizza of thickness a and RADIUS z,

If we assume the pizza is cylindrical of radius z and height a, then the volume is
V = π*z^2 * a = Pi*z*z*a

And if you take that height to be ‘a’ and it’s radius to be ‘z’ its volume is equal to pizz*a

I used pizza to help my kids calculate the volume of a cylinder. Imagine a pizza is a squat cylinder of height ‘a’ and radius z. It’s volume is therefore pi.z.z.a

A pizza that has radius “z” and height “a” has volume Pi × z × z × a .A pizza is basically a very short cylinder, and that’s how you calculate its volume. https://myatechedu.wordpress.com/2019/03/02/a-pizza-that-has-radius-z-and-height-a-has-volume-pi-x-z-x-z-x-a-a-pizza-is-basically-a-very-short-cylinder-and-thats-how-you-calculate-it/

Pizza is a rather flat cylinder.
The Volume of any cylinder BurritoDrum🛢 is: V (cylinder) = Pi*r^2*h
If z is the radius and a is the height (or depth) then

What do you mean? If the pizza is a cylinder (which is part of the joke) and the base has a radius z and the cylinder has height a, then its volume is given by
V = πz^2a, or
V = Pizza

The volume of a pizza with radius z and height a is pi z z a!
A pizza is approximately the shape of a cylinder, so to get its volume, we have to multiply its area by its height. Thus the volume V of a pizza with height a is given by
V=a⋅ A = pi ⋅ z ⋅ z ⋅ a! That’s it.

Assuming #pizza is a perfect cylinder:
