To find the volume of the solid obtained by rotating the region enclosed by the curves y = e, y = 0, x= 0 and x= 12 about the y-axis, we use the cylindrical shells method and rotate a vertical strip around the y-axis creating a cylinder with radius r = and height h = Therefore the volume can be found from the integral V = 2 m After evaluating the integral we find that V = dx
