“What is the volume of an object with depth a and radius z?"/"Pi z z a.”

A popular mathematical pizza joke that has been printed on posters is:

Q: What is the volume of an object with depth a and radius z?
A: Pi*z*z*a.


The joke has been cited in print since at least 1997.

Silly ObPuzzle:  My local pizza delivery company is called Perfect Pizza.  This means that not only do the pizzas taste perfect but they are also perfectly circular and perfectly uniform in depth.  They’ve just delivered a pizza with depth a, and radius z.  What is its volume?

Today I Found Out
THE MATHEMATICAL VOLUME OF A PIZZA IS PIZZA
March 12, 2010 Daven Hiskey
Today I found out that the mathematical volume of a pizza is pizza.  How does that work you say?  Well if z = radius of the pizza and a = the height then Π * radius2 * height = Pi * z * z * a = Pizza.

If you have a pizza with radius “z” and thickness “a”, its volume is Pi(z*z)a (i.imgur.com)
