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?
