Please help me with these questions with explanation. I will gladly rate you.

Use the method of cylindrical shells to find the volume of the solid generated by rotating the region bounded by the curves y = e *, y = 0, x = -1, and x = 0 about the line x = 1. Volume =Using disks or washers, find the volume of the solid obtained by rotating the region bounded by the curves y = 1/x, y = 0, x = 1, and x = 4 about the x-axis. Volume =Use calculus to find the volume of the following solid S: The base of S is the parabolic region {(x, y)| x2 5 y 5 1}. Cross-sections perpendicular to the y- axis are squares. Volume =
