How do i calculate the surface integral(adsbygoogle = window.adsbygoogle || []).push({});

[itex]∫∫xdS[/itex] where [itex]z=x^{2}[/itex] is the parabolic cylinder

over the area [itex]x^{2}+y^{2}=1[/itex]

I do not know how to solve this task because i cant express the surface parametrization in r(x,y).

But when i express it as g(x,z)=0 i get the double integral dependet on dxdz. But i cant use this when the circular transformation is rdrdθ=dxdy
