Surface Area of a Sphere
2014-11-30 09:21
This GeoGebra example demonstrates the surface area of a sphere through 3D geometric construction. Using Sphere, Cylinder, and IntersectPath commands, it builds a visual model illustrating the classic relationship between a sphere's surface area and the lateral surface area of its circumscribed cylinder (Archimedes' theorem: the surface area of a sphere equals the lateral area of the enclosing cyl
