2) Consider the region bounded by y = In (x + 1), the line y = 1 and the y-axis. Our goal is to determine an expression for the volume of the solid of revolution by doing the following: [5 pts] _"J a) Sketch on the picture above, the solid created by rotating this region about the y-axis. b) Draw a representative slice of the solid. 0) Give a specific expression for the volume of that slice
