You didn't give me anymore info, I don't know if there is more. Changing r to rectangular I it is a half circle, 0 to pi.

you don't need more. If you graph it you'll know. It's a cardiod, so the limits are 0 to 2pi, if I remember correctly

and the thing you would be integrating is r dr dtheta don't forget the r!
