There is a thin uniform disc of radius R and mass per unit area 
, in which a hole of radius R/2 has been cut out as shown in the figure. Inside the hole, a square plate of same mass per unit area 
is inserted so that its corners touch the periphery of the hole. The distance of the center of mass of the system from the origin is
