Use cylindrical coordinates to evaluate the integral where R

Use cylindrical coordinates to evaluate the integral where R is the cylinder x^2 4- y^2

Solution

Since I am not able to draw intergral sign I use intg for integral

intg(intg(intg))xy dxdydz =

intg(intg) ((x^2y/2) + c) dydz

intg(cy +(1/4)x^2y^2 + c)dz

(c+cy+(1/4)x^2y^2)z + c
