This GeoGebra example dynamically demonstrates the volume of a right circular cone, visually linking the base radius, height, and the resulting volume. The core mathematical concept is the solid geometry formula V = (1/3)πr²h for a cone, along with 3D construction and measurement. The construction uses the Cone command to create the cone and the Segment command to define the radius and height segments, with objects such as A, B, r, h, C, and others serving as adjustable parameters. Sliders or buttons (button1, button2) allow users to change the radius and height, while text objects (text1, text2, text3) display the updated volume and intermediate calculations. This resource is suitable for middle and high school students learning solid geometry, and is ideal for classroom demonstrations or self-guided exploration of how changing dimensions affects the volume.
