This example demonstrates how to create a surface of revolution of a function in the xy-plane around the y-axis. Key math concepts include surface of revolution, function graph, and 3D geometry. The construction uses GeoGebra's Function and Surface commands to generate the function f(t) and its rotated surface, suitable for high school and above students learning about solids of revolution in calculus.
