I’m trying to integrate the surface of a cylinder.

I know when integrating the surface of a cylinder the surface element is:

ρdØdz

Where ρ² + z² = r²

And for a sphere it is:

r²sinθdθdØ

In a sphere r=ρ

But in a cylinder when I’m integrating its surface, could it be written as:

(r² - z² )½ . dθ.dz

For example ∫∫zdS over a cylinder from 0<z<5 and 0<Ø<2π

Would it be:

∫∫z. (r² - z² )½ . dθ.dz ?
