Let $R$ be the triangular region bounded by the lines $y=\frac{5}{5}1,y=26-2x$ and $y=2.$

$($c$)$ Use the washer method to set up an integral $($or a sum of integrals$)$ that comprites the wolume of the solid chalsed loy revolving $R$ shout the $x$ axis. Do not evaluate the integral$($s$).$

$($b$)$ Use the washer method to set up an integral $($or a sum of integrals$)$ that computes the volume of the solid obtained by revolving $R$ about the horizontal line $y=10.$ Do not evaluate the lnitegral$($s$).$
