This example demonstrates the calculation of the volume and surface area of cylinders. Key mathematical concepts include the geometric properties of cylinders, and the formulas for calculating volume and surface area. Using GeoGebra commands such as Line, Point, Ellipse, Vector, Translate, etc., the construction process of the cylinder can be dynamically shown. Suitable for middle and high school students learning geometry and solid geometry.

AI Drawing Prompt Reference

Draw a cylinder to demonstrate the calculation of its volume and surface area. Start by sketching the base circle and the lateral surface, then mark key points like the center and tangent points. Connect these points to form the cylinder's outline. Next, calculate and display the formulas for volume and surface area, using dynamic transformations to show the geometric properties of the cylinder.
