More About Cone
 Right Cone: A right cone is a cone in which the vertex is aligned directly above the center of the base. The base need not be a circle here.
 Right Circular Cone: When the base of a right cone is a circle, it is called a right circular cone. In a right circular cone, each point on the circle is equidistant from the vertex of the cone.
 Oblique Cone: When the vertex of a cone is not aligned directly above the center of its base, it is called an oblique cone.
