Hi, could you please help me with the following problems? Thank you very much!

2. Solve (xe 27) dx + (x4+ 2x2y?) dy, where C is the boundary of the region between the circles x* + y = 1 and x2 + 32 =4. Make sure to include a sketch of the region, its boundary C and proper orientation. [ 5 pts ] 3. Solve F . dr, where F(x, y, z) = (xy, 2z, 3y) and C is the curve of intersection of the plane x + z = 5 and the cylinder x2 + y2 = 9. Assume C has a counterclockwise orientation from a top view.
