Assuming the result that the centroid of a solid hemisphere lies on the axis of symmetry three-eighths of the way from the base toward the top, show, by transforming the appropriate integrals, that the center of mass of a solid semiellipsoid, given below, lies on the z-axis three-eighths of the way from the base toward the top. (You can do this without evaluating any of the integrals.) $1,220 a 62 Let E be the semiellipsoid and H be the hemisphere...

1. Using polar coordinates in the x-y plane, find the volume of the solid above the cone z r and below the hemisphere z= v8-r2. As a check the answer is approximately 13.88 but of course you have to calculate the exact answer 2. At the right is the graph of the 8-leafed rose r 1+2cos(40) Calculate the area of the small leaf. As a check the answer is 0.136 to 3 places of decimal (But of course you have...
please solve both parts! Find the center of mass of a solid of constant density bounded below by the paraboloid z=x+y and above by the plane z = 144. Then find the plane z = c that divides the solid into two parts of equal volume. This plane does not pass through the center of mass The center of mass is (000.
