This GeoGebra example dynamically demonstrates the calculation of cone volume, intuitively showing the derivation of the volume formula V=1/3πr²h. Core mathematical concepts include: geometric properties of cones, volume calculation formulas, applications of definite integrals, and the concept of limits in solid geometry. Construction highlights: Use the Cone command to create a 3D cone model, draw auxiliary line segments with Segment commands to determine height and base radius, mark key points with Point commands, and implement interactive demonstrations with button controls. Slider animations allow dynamic parameter adjustments to observe volume changes. Suitable for middle school solid geometry teaching, higher mathematics definite integral visualization, and as an auxiliary tool for geometric intuitive teaching.
