    Calculus

    I need to find the limits of the integral, I solved it with polar coordinate (I think it's called like that...) but I'm not sure it's correct.

    Do I need to go back to x and y in the solution?

    Is this

    \iint_{R}f(x,y)~dx~dy

    Where R=\left\{(x,y):x^2-2x+y^2-6y+9\leq{0}\right\}?

    Looks fine except for one small thing - your final answer is missing the r in the integrand from the Jacobian.
