Hello! I need help with following Gauss' theorem problem.. Thank you in advance..!

Let W be the (right) circular cone 0' of height 1 in R3, whose base B is the unit disk centered at the origin laying in the my-plane, that is, B = {(m, y, 0) : $2 + y2 g 1}. Note that the apex of the cone is the point (0, 0, 1). Calculate f fag F - 613, where F(a:, y, z) = (:13, 2y, 22) and 30 is the boundary of 0 (including the base B)
