Volume Calculation and Differentiation of Cones, Cylinders, and Spheres

This example demonstrates the volume calculation and calculus application of cones, cylinders, and spheres, showing the relationship between volume and geometric parameters dynamically. Core mathematical concepts include solid geometry volume formulas, differentiation and integration in calculus, and limit concepts. GeoGebra commands like Cone, Cylinder, Segment, Distance, and Vector are used, along with objects such as H, R, r, h, O, A, a, c, b, B, d, e, f, g, V, F, G, i, button1, button2, distanceGF, TextGF, C, j, D, u, text1, text2, text3, n, text4. Suitable for high school and above, covering solid geometry, calculus, and geometric modeling for teaching demonstrations and exploratory learning.
