What is the square root of pizza?

pie

actually its quite simple...

you take the thickness of the crust which is a

then you take the side of the slice and double it which is z to the second (z^2)

then you take the entire Pizza and make it pi

the slice's angle from the tip to the crust will be V

when you have figured this out it becomes this

V=piz^2a

(slice=pizza)
