Surface area inside an elliptic cylinder

  1. Nov 18, 2009 #1
    1. The problem statement, all variables and given/known data

    Find the surface area of that part of the plane 8x+3y+z=9 that lies inside the elliptic cylinder (x^2/64) + (y^2/9) =1

    2. Relevant equations

    not sure what equations i need to use. probably parametrization of a region

    3. The attempt at a solution

    i'm not quite sure how to start this problem. how do i related the elliptic cylinder with the plane?

    Hi MasterWu77! :smile:

    You could just say it's a projection, and divide the base area of the cylinder by the appropriate cosine. :wink:

    ok but how would i say that it is a projection and what exactly do you mean by the appropriate cosine?
