Bonus. (8 pts) Many of the definitions we used for two-dimensional mass and moments can be extended to three dimensions rather easily. For example, mass = ESSA 1, 2) av would represent the mass of the solid Q where p(x, y, ) is the density at any point (x, y, z). Find the mass of the solid bounded laterally by the cylinder 2? + y2 = 2x and bounded above and below by the cone x2 = x2 + y2....

(1 point) The motion of a solid object can be analyzed by thinking of the mass as concentrated at a single point, the center of mass. If the object has density p(x, y, z) at the point (2, y, z) and occupies a region W, then the coordinates (@, y, z) of the center of mass are given by = NNW updv y= ST ypdV = .SIL apav, m Assume x, y, z are in cm.
