Let f be the function defined by f(x) = −ln(x) for 0 < x ≤ 1. R is the region between the graph of f and the x-axis. 1. This question does not permit the use of a calculator.
Determine whether region R has a finite area. If so, find the area. If not, explain why.

2. This question does not permit the use of a calculator.
Determine whether the solid generated by revolving region R about the y-axis has a finite volume. If so, find the volume. If not, explain why.
