Using polar coordinates, evaluate the integral ff sin(m2 + y2)dA where R is the region R 9 g $2 + y2 s 49- C] By changing to polar coordinates, evaluate the integral ff (132 + y2)11/2dA where D is the disk 2:2 l y2 g 36. D The value is C]. Use polar coordinates to find the volume of a sphere of radius 7. C] Find the volume of the ellipsoid x2 + y" + 522 = 25.Find the volume of the solid enclosed by the paraboloids z = 25 (x2 + 2) and z = 18 - 25 (x2 + 32).A cylindrical drill with radius 3 is used to bore a hole through the center of a sphere of radius 5. Find the volume of the ring shaped solid that remains. Cl A volcano fills the volume between the graphs 2: = 0 and z = 25, and outside the (w2 + 2112) cylinder :32 l y2 = 1. Find the volume of this volcano. C]
