Cylinder, cone, and sphere – surface area and volume

Mathematics3D GeometryAges 14–15

A 3D model of a cylinder, cone, or sphere that can be rotated by dragging with the mouse or a finger. Drag the radius R and height h sliders to see the solid change along with the lateral surface area, total surface area, and volume formulas (Sxq = 2πRh, V = πR²h; Sxq = πRl, V = ⅓πR²h; S = 4πR², V = ⁴⁄₃πR³) shown with actual numbers.
