To make a cone of given slant length l and base circumference.
A cone is a solid that has a circular base and a single vertex, called apex. If the vertex is exactly over the center of the base circle, it is called a right cone, else it is called an oblique cone.
Height (h):The distance from the apex of a cone to the base. Formally, the shortest line segment between the apex of a cone and the base.
Radius (r): It is the radius of the base.
Slant Height (l): The diagonal distance from the apex of a right circular cone to the base.
