Write but do not evaluate, an integral expression that gives the volume of the solid generated when R is rotated about the horizontal line y=1. 2. Region R is the base of a solid. For each y, where 1≤y≤3, the cross section of the solid taken perpendicular to the yaxis is a rectangle whose height is half the length of its base. Write, but do not evaluate, an integral expression that gives the volume of the solid.
