Surface Integral of a Cylindrical Surface

  1. Nov 30, 2011 #1
    1. The problem statement, all variables and given/known data

    What is the integral of the function x^2z taken over the entire surface of
    a right circular cylinder of height h which stands on the circle x^2 + y^2 = a^2


    2. Relevant equations



    3. The attempt at a solution
    My problem is writing the equation in cylindrical form if that makes any sense. Do I just use the equation of the circle?

    You have to write a double integral in polar form.
    You may find useful to remember that: [itex]r^2 = x^2+y^2[/itex] and [itex]x = r\ \cos \theta[/itex]
