1. The problem statement, all variables and given/known data Evaluate the double integral (x+2y)dA, where R is the region in the first quadrant bounded by the circle x^2+y^2=9. 2. Relevant equations None. 3. The attempt at a solution I know how to evaluate the double integral but I just don't know how to find the limits of integration. I know that the radius of the circle is 3.
