Cylinder Geometric Construction and Volume Demo

This example demonstrates the 3D geometric structure of a cylinder and its volume calculation process. Core concepts include solid geometry, cylinder definition, volume formula V=πr²h, and relationships between radius and height. Construction utilizes GeoGebra's Cylinder command to generate the body, Point objects to define key vertices, Segment to build auxiliary lines, and Volume command to display numerical values in real-time. Suitable for middle school students learning spatial geometry or teachers for dynamic classroom demonstrations to understand abstract solid figure properties.
