Volume Calculation Using the Washer Method

The video tutorial explains how to calculate the volume of a solid formed by rotating a region bounded by the equations x = 9.5y and x = y^3 about the y-axis. The washer method is used, involving setting up the integral with respect to y, determining the limits of integration by solving the system of equations, and evaluating the integral to find the volume. The tutorial concludes with the final volume calculation.
