Question

Calc 3 Please Help!!!

Answer 1

Parameterize your surface using x and z. This gives you your integration bounds.

Answer 2

\[\iint_S f(x,y,z)dS=\iint_{\Phi}f(\Phi(u,v)) \left|\frac{\partial \Phi}{\partial u} \times \frac{\partial \Phi}{\partial v}\right|du dv\]
So use x and z for your u and v. Find the cross product, then the magnitude. Evaluate the function z and the parametization (since using z as parameter then z=z for this) and integrate!
