M(Rcm)=\int(rdm)

3. The attempt at a solution

Okay, so I've figured out that I have to integrate the radii by the mass element dm, which in this case would be p, because that's the mass/unit area? I think that's right, but even there I'm not sure and the actual integral itself I have no idea how to do for such a weird shape.
