Find the center of mass of the following solid, assuming constant density. Sketch the region and indicate the location of the centroid. Use symmetry when possible and choose a convenient coordinate system. The region bounded by the paraboloid z = x2 + y and the plane z = 121. . . . Determine the triple integral to be used to most efficiently find Myy, the solid's moment with respect to the xy-plane. Use increasing limits of integration. Assume a density of 1. Use cylindrical coordinates. 000 Mxy = dz r dr de (Type exact answers.) 000 The center of mass, in Cartesian coordinates, is located at (10.). (Type exact answers in simplified form.)
