1. A cylinder of radius, r=3, and height, h=4, is centered at the origin and oriented along the z axis. A vector field can be expressed in cylindrical coordinates as,
 \vec\mathfrak F = (2.35+2.57z)\rho^3\hat\rho +7.45z^3\hat z
Let \hat n be the outward unit normal to this cylinder and evaluate ,
 \left |\int_{top}\vec\mathfrak F\cdot\hat n dA\right|\,
over the top surface of the cylinder.
