Find the volume of the following solid. The solid above the region R = {(x,y): 0 s x =3, 0sy=3 -x} Z=18-x -y bounded by the paraboloids z = x2 + y and z = 18 - x2 -y and the coordinate planes in the first octant Z=X + R The volume of the region is cubic units. (Simplify your answer. Type an integer or a fraction.)Use double integrals to compute the area of the region bounded by the parabola y = 2x2 and the line 3!: 8. The area is El square units. (Simplify your answer.)
