I am having some trouble with these 2 problems. Thank you so much for your help.

1) The solid bounded between the paraboloidz=x2+y2 and the plane z = 4 has density function (x, y, z) =z+11

a) Sketch the solid and draw the region in the xy-plane over which you are integrating

b) Set up the integral to find the mass of this solid in both rectangular and cylindrical coordinates

2) EvaluateC2x+yds along the path on the quarter circle of radius 3 from (3,0) to (0,3)
