Homework Help: Surface integral

  1. Feb 22, 2010 #1
    1. The problem statement, all variables and given/known data

    Let S be the boundary of the region {(x,y,z) : 0<z<h , a^(2)<x^(2)+y^(2)<b^2 , and a<b

    F is defined at the point with position vector r=(x,y,z) by

    F(r)=exp (x^2+y^2)r

    Evaluate the surface integral

    [tex]\int[/tex] F.n dS

    Where n is the outward pointing unit normal to the surface S

    3. The attempt at a solution

    How do i calculate the normal, and what are the limite on the integral?

    First draw the surface [tex]S[/tex]; what does it look like?
