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

    2. Relevant equations


    3. The attempt at a solution

    ∫∫ re-r^2 drdΘ

    I'm not sure how to establish the boundaries. This is an online class so if you can offer any additional tips for evaluating types of integrals of this sort, that would be great. Thank you.

    Try to graph the region.
    If you want to approach it purely algebraically, the bounds are 0 < x < 1, 0< y < √(1-x2). Substitute the polar forms for x and y.
