### Cone

The cone is a three-dimensional solid figure with a circular base and a vertex. If a perpendicular straight line connect the
vertex to the base midpoint, the cone is called a right cone. Otherwise, it is an oblique cone. In all cases, this straight line also is the cone height.

Cone elements:

• Base: surface of the circle of the cone base;

• Radius: radius of the cone base;

• Base surface: base area of the cone;

• Lateral surface: curved surface connected by the apex of the cone and the circumference;

• Vertex or apex: a fixed point where all the points of the lateral curve, not connected to the base are joined;

• Height: perpendicular distance from the cone base plane to the apex;
