Shell method Volume of a solid problem

Here's the problem:

Use the Shell Method to compute the volume of the solids obtained by rotating the region enclosed by the graphs of the functions https://webwork.math.lsu.edu/webwork...394a860011.png, https://webwork.math.lsu.edu/webwork...16fea26871.png and https://webwork.math.lsu.edu/webwork...3084628a01.png about the y-axis.

I can solve problems when I am given one or two functions, an interval, and an axis to rotate about...but I am completely lost on how to solve this kind of problem. Any help would be great, thanks>
