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.

Isn't the volume \[V=\pi \int\limits_{0}^{4}((1(3√x))^2 (11)^2) dx\]
