Chapter 6.11, Problem 6P

Use either Stokes' theorem or the divergence theorem to evaluate each of the following integrals in the easiest possible way.

${\displaystyle \iint \text{V}}\cdot nd\sigma$ over the closed surface of the tin can bounded by $x^2+y^2=9,z=0$ $z=5,$ if $V=2xyi-y^{2}j+(z+xy)k$.
