This example demonstrates the relationship between the height of water and the volume change in a cone when filling or draining it, involving core math concepts like related rates, differential equations, integral calculus, and the cone volume formula. It uses GeoGebra commands such as Intersect, Segment, Distance, Mirror, Ellipse, Point, Polygon, OrthogonalLine, Ray, Angle, and Textfield for construction. Suitable for high school and above students learning calculus and its applications.

AI Drawing Prompt Reference

Draw a cone and show the relationship between the height h of water and the volume change when filling or draining it. Start by drawing the base and side of the cone, then draw a vertical line segment to represent the height h, followed by drawing the water level line segment and marking the intersection points of the water level line with the cone's side. Finally, use these points to construct a triangle representing the cross-section of the water level line with the cone's side.
