Explore: Circular Cones

of circular cones are not usually special; in fact one is often interested in polyhedral cones. An even more general concept is the topological cone, which

conics play an essential role answering the question: "Which right circular cones contain a given ellipse or hyperbola or parabola (see below)". Focal

representations of them also influence the shape of the ruled surface. A right circular cylinder is given by the equation x 2 + y 2 = a 2 . {\displaystyle x^{2}+y^{2}=a^{2}

the surface created by joining two congruent right circular cones at their bases. A bicone has circular symmetry and orthogonal bilateral symmetry. For a

volcanic cones include stratocones, spatter cones, tuff cones, and cinder cones. Stratocones are large cone-shaped volcanoes made up of lava flows, explosively

angle in the form of a circular cone can be projected onto a sphere from its centre, delineating a spherical cap where the cone intersects the sphere.

elliptical cone is a cone with an elliptical base. It is a generalization of the circular cone and a special case of the generalized cone. The term might

Archimedes, who also used the term "solid rhombus" for a bicone, two right circular cones sharing a common base. A planar rhombus is a cross section of a bicone

revolution has circular symmetry around an axis, also called cylindrical symmetry or axial symmetry. An example is a right circular cone. Circular symmetry
