- The region bounded by the graphs of $y=e^x$, $y=0$,$x=0$, and $x=1$ is revolved about the
x-axis. Find the volume of the resulting solid.
- Find the volume of the solid obtained by rotating the region bounded by $x=3\sqrt{(y-1)}$,
$x=0$, and $y=2$ about the y-axis.
- Find the volume of the solid obtained by rotating the region bounded by $y=\sqrt{(x+1)}$, and
$y=\frac{1+x}{2}$ about the x-axis.
- Find the volume of the solid obtained by rotating the positive region bounded by $y=x^3$, $y=x$
- Find the volume of the solid obtained by rotating the region bounded by $y=3-cosx$, and $y=4$ about $y=1$.
