Volume of a Surface of Revolution from Two Curves

This example demonstrates the calculation of the volume of a surface of revolution generated by rotating a region bounded by two curves. Key mathematical concepts include integration, volume formulas for solids of revolution, and geometric transformations of function graphs. The construction uses GeoGebra's Surface command along with objects like α, f, g, a, b for parameterization and function definition. Suitable for high school and above students to understand the calculation of volumes of solids of revolution and transformations of function graphs in calculus.
