    Try finding the center of mass of what the entire mass would be and what the center of mass of the cutout would be. The center of mass of the entire disk (the origin) will be the weighted average of the cutout and the residual disks' centers of mass.

    x=(m1x1+m2x2)/(m1+m2). And you find x=R/3, situated to the left of the previous center of mass.
