If you have a pizza with radius "z" and thickness "a", its volume is Pi(z*z)a 

Love it!  No wonder I like pizza as much as I do.
 

The geek in me has already shortened this to pi(zz)a.

Yes the geek in me should have as well. That'll teach me to copy and paste things wholesale from less than optimum geeky sources.

Funny that you should mention pizza and the Italians (and I'm not referring to the Leaning Tower of Pizza either  ).  When I was in Italy (way back in 1981), I ordered pizza from one of the eating establishments there.  What I got was pita bread covered with tomatoes that had been "rolled out" over the top then covered with cheese and olives.  It was awful (except for the cheese) and the olives had pits in them...
 
No, America really created pizza as its known now (and I love the stuff!).

 
Coincidentally...
 
I fancied a pizza last night so I phoned Dominoes and ordered a thin and crusty supreme...
 
They sent me Diana Ross.
