questions below:

Describe the given region in polar coordinates. The lower portion of the region is S 65 , SrS (Type an exact answer, using 1: as needed.) . The upper portion of the region is 565 SrS Change the Cartesian integral into an equivalent polar integral. Then evaluate the polar integral. 9 V81 -x2 In (x2 + y2 + 1) dy dx 181-X Change the Cartesian integral into an equivalent polar integral. 181 -x2 In (x2 + y2 + 1) dy dx = dr de 181 -x2 (Type exact answers, using it as needed.) The value of the double integral is (Type an exact answer, using it as needed.)
