Use the Divergence Theorem to evaluate the flux \(\iint_{\mathcal{S}} \mathbf{F} \cdot d \mathbf{S}\).

\(\mathbf{F}(x, y, z)=\left\langle x y^{2}, y z^{2}, z x^{2}ightangle, \mathcal{S}\) is the boundary of the cylinder given by \(x^{2}+y^{2} \leq 4,0 \leq z \leq 3\).

THEOREM 1 Divergence Theorem Let S be a closed surface that encloses a region W in R. Assume that S is piecewise smooth and is oriented by normal vectors pointing to the outside of W. If F is a vector field whose components have continuous partial derivatives in an open domain containing W, then Jfv. ds = [1, div(F) dV 1
