It would be 2PiZA, since ZZ is Z squared

EDIT: my bad, I was thinking of circumference

[–] [email protected] 6 points 10 months ago

Wat? It is supposed to be squared though...

That would be the surface area of the crust, not the volume

[–] [email protected] 1 points 10 months ago (1 children)

How does that work out? It doesn't take into account how large the crust is in relation to the rest of the pizza.

[–] [email protected] 1 points 10 months ago (1 children)

Sorry, the surface area of the "vertical" side of the crust, not including the top or bottom surfaces.

[–] [email protected] 1 points 10 months ago (1 children)

Still not right, I think. That would be 2πZ, not 2πZa, right?

[–] [email protected] 2 points 10 months ago (1 children)

No, you need to include the height of the cylinder (a). Imagine a deep dish pizza (big a) versus a thin crust (small a) - the sides of the deep dish pizza have more area. Your formula returns the circumference of the pizza.

If you're interested in dimensional analysis (and why wouldn't you be?) the formula you proposed doesn't have enough length units. It would return a value of length (like inches, or cm) not area (like square inches or square cm).

Oh gosh, my mistake. Had just woken up.

It's a 2-for-1 deal! Like Little Caesar's! Pizza pizza.
