A solid is formed by revolving the curve y=x2²/3 +1, 0≤x≤ 2.5, about the x-axis. Estimate the volume of the solid by partitioning [0, 2.5] into five subintervals of equal length, slicing the solid with planes perpendicular to the x-axis at the subintervals' left endpoints, and constructing cylinders of height 0.5 based on cross sections at these points, as shown below.
