A thin rectangular plate of uniform areal density σ = 2.79 kg/m2 has length of 37.0 cm and width of 23.0 cm. The lower left hand corner is located at the origin, (x,y)= (0,0) and the length is along the x-axis.
(a)There is a circular hole of radius 8.00 cm with center at (x,y) = (12.50,9.50) cm in the plate. Calculate the mass of plate.
(b)Calculate the distance of the plate's CM from the origin
