Problem # $1$:

Use Stokes' Theorem to evaluate ${\displaystyle \underset{C}{\overset{\phantom{}}{}}}F*dr$ where $F=(x+9z)i+(7x+y)j+(3y-z)k$ and $C$ is the curve of

intersection of the plane $x+4y+z=16$ with the coordinate planes.

$($Assume that $C$ is oriented counterclockwise as viewed from above.$)$
