    Hint: sketch it. Upload your pic here to show us at least that you are trying. Then we will take it from there.

    Ok. I also expected that you sketch into it a "thin cylindrical shell".

    At x = x, sketch a thin vertical rectangle (of width dx) in your domain.

    Rotate it around the y axis. 

    Whats the volume of this thin cylindrical shell?[thats high school geometry, so you should be able to do that]. 

    Write it here and then we will take it from there if need be.
