This GeoGebra applet dynamically demonstrates the unfolding process of a cylinder's lateral surface. Using sliders to control the height and base radius, along with rotation and conditional commands, it simulates cutting the lateral surface along a generatrix and flattening it into a rectangle. This model intuitively reveals the geometric origin of the cylinder's lateral area formula, helping stud
