# Find flux through a surface

1. The problem statement, all variables and given/known data

If vector $A=(2x,-z^2,3xy)$, find the flux of A through a surface defined by $ρ =2, 0<\phi<\pi/2, 0<z<1$

2. Relevant equations

divA?

3. The attempt at a solution
Can I use divergence here?
This is a closed surface correct? Is this is a cylindrical wedge?
Also do I need to convert the vector field to cylindrical form? Or the defined surface to rectangle form?

If I used divergence do I divide my answer by 4 since the wedge is a 1/4 of the cylinder?

Thanks
