    1. The problem statement, all variables and given/known data

    Sketch the region enclosed by the given curves. Decide
    whether to integrate with respect to x or y. Draw a typical approximating
    rectangle and label its height and width. Then find the
    area of the region

    2. Relevant equations



    3. The attempt at a solution
    I got a negative answer again :(

    Same answer as before. You subtract the curve on the top minus the curve on the bottom and integrate. Not vice versa.

    Yes, don't forget you were going to multiply by two. Are you sure you know why you can do that?
