Practice Another Set up, but do not evaluate, an integral for the volume of the solid obtained by rotating the region bounded by the given curves about the y=ln(x), y=0, x=7; about the y-axis. What is the integral for the volume of the solid generated by rotating the region bounded by the curves y=ln(x), y=0, and x=7 about the y-axis?
A) ln(x),
B) 0,
C) x=7,
D) y=ln(x).
