Centroid of Solid

Volume by integration and finding the centroid

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

Integral calculus: volume and centroid of the solid

Please help po dito

Region 1 is bounded by the x axis, the line x=1 and the curve y=x^2.find the volume and centroid of the solid generated when the indicated region is revolved about y axis and revolved about x axis

Centroid of volume formed by rotating about the y-axis the area bounded by 3 lines

Centroid of the solid generated by the area Bounded by y=x, y=3x and X + Y= 8 about y axis
