\noindent {\bf Problem statement} Suppose $R$ is the region enclosed
by the curves $y=\ln x$, $y=0$, $x=1$ and $x=e$. Find the area $A$ of
$R$, find the volume $V_1$ of the solid object formed when $R$ is
revolved about the $x$-axis, and find the volume $V_2$ of the solid
object formed when $R$ is revolved about the $y$-axis.
