Find the center of mass (centroid) of the following thin, constant-density plate. Sketch the region corresponding to the plate and indicate the location of the center of mass. Use symmetry whenever possible to simplify the work. The region bounded by y = 13 sin x and y = 0 between x = 0 and x = T The center of mass is . (Type an ordered pair. Type an exact answer, using t as needed.) Which of the following shows the plate and the center of mass? A. . OC. D. Ay 13- 13- 13- 13- X 2 2 N a-
