III.) (20)

Use polar coordinates to evaluate Dx2+y2dA where D is the part of the disk x2+y2=9 that lies above the x -axis. Sketch the region of integration.

IV.) (20) Set up a triple integral in cylindrical coordinates to find the volume of the region above the paraboloid z=x2+y2 and below the plane z=16 . (DO NOT INTEGRATE OR EVALUATE)

V.) (20)   Set up a triple integral in spherical coordinates to find the volume of the solid above z=0 , below the cone z=x2+y2 and inside the sphere x2+y2+z2=16 in the first octant. (DO NOT INTEGRATE OR EVALUATE.)

PART D: Several years ago Polar Inc. acquired an 80% interest in Icecap Co. The book values of Icecap's asset and liability accounts at that time were considered to be equal to their fair values. Polar’s acquisition value corresponded to the underlying book value of Icecap so that no allocations or goodwill resulted from the transfer. The following selected account balances were from the individual financial records of these two companies as of December 31, 2018: Assume that Icecap sold...
