Question

Having some trouble here...
Sketch the region bounded by y = 1, x = e^4, and y = ln(x). Give one or more definite
integrals that describe the volume of the solid obtained by rotating this region about the
line y = -2 DO NOT EVALUATE THE INTEGRAL.

Answer 1

\(x=e^4\) is a vertical line \(y=1\) is a horizontal line

Answer 2
