Surface and Volume Applets
This example demonstrates the relationship between the surface area and fixed volume of a cylinder. Key mathematical concepts include cylinder geometry, surface area calculation, and volume constraints. Construction involves using GeoGebra commands to define cylinder parameters such as radius, height, and surface area, and observing changes in surface area by adjusting parameters. Suitable for high school mathematics to understand solid geometry and function relationships.

AI Drawing Prompt Reference
Draw a cylinder with a fixed volume, illustrating how its surface area changes with dimensions. Start with a 3D cylinder showing a circular base and a rectangular lateral surface, with radius and height labeled. Beside it, plot a curve representing surface area as a function of radius, which decreases then increases, with a minimum point. Use dashed lines for the cylinder's axis and arrows to indicate how surface area changes as radius varies. Keep the composition clear to emphasize the geometric and functional relationship.
