Help me solve this problems.Thanks. :)

(x²+4) y' + 3 xy = x

please help me with this!!!
Im really having hard time getting this.
Region 1 is bounded by the x axis, the line x=1 and the curve y=x^2. Region 2 is bounded by the two curves y=x^2 and x=y^2. Region 3 is bounded by the y axis, the line y=1 and the curve x=y^2. Find the volume and centroid of the solid generated when the indicated region is revolved about the given line:
A. Region 1 is revolved about y axis
Region 1 is revolved about x axis
B. Region 2 is revolved about y axis
Region 2 is revolved about x axis

Hello,

Can anyone help to solve this question????

Please help me again to solve this.

(e^2y-ycosxy)dx-y(1-x²)dy=0

(xy + (y/x) + (3/x) -2) dy + y² dx = 2(1+(y/x))dx
