- This file illustrates a cone and its main caracteristics. Labeled “r” is the radius of the circular base. Labeled “h” is the height, from center of base to apex, of the cone. Labeled “c”, is the slant height of the cone. Labeled “θ” is the angle between the height and the slant height.
- Cone (Wikipedia)
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex.
