Cone vs. Cylinder — What's the Difference?

Difference Between Cone and Cylinder

Definitions

Cone➦

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. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base that is in a plane that does not contain the apex.

Cylinder➦

A cylinder (from Greek: κύλινδρος, romanized: kulindros, lit. 'roller', 'tumbler') has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. It is the idealized version of a solid physical tin can having lids on top and bottom.

Cone➦

(Physiology) One of the photoreceptors in the retina of the eye that is responsible for daylight and color vision. These photoreceptors are most densely concentrated in the fovea centralis, creating the area of greatest visual acuity. Also called cone cell.

Cylinder➦

Cone➦

Cylinder➦

Cone➦

(geometry) A surface of revolution formed by rotating a segment of a line around another line that intersects the first line. Category:en:Surfaces

Cylinder➦

(geometry) A surface created by projecting a closed two-dimensional curve along an axis intersecting the plane of the curve. Category:en:Surfaces

When the two-dimensional curve is a circle, the cylinder is called a circular cylinder. When the axis is perpendicular to the plane of the curve, the cylinder is called a right cylinder. In non-mathematical usage, both right and circular are usually implied.

(geometry) A solid of revolution formed by rotating a triangle around one of its altitudes.

Cylinder➦

(geometry) A solid figure bounded by a cylinder and two parallel planes intersecting the cylinder.

Cone➦

(topology) A space formed by taking the direct product of a given space with a closed interval and identifying all of one end to a point.

Cylinder➦

Any object in the form of a circular cylinder.

Cone➦

Anything shaped like a cone.

Cylinder➦

A cylindrical cavity or chamber in a mechanism, such as the counterpart to a piston found in a piston-driven engine.

Cylinder➦

The part of a revolver that contains chambers for the cartridges.

Cone➦

A unit of volume, applied solely to marijuana and only while it is in a smokable state; roughly 1.5 cubic centimetres, depending on use.

Cylinder➦

(computing) The corresponding tracks on a vertical arrangement of disks in a disk drive considered as a unit of data capacity.

Cone➦

(anatomy) Any of the small cone-shaped structures in the retina.

Cylinder➦

(transitive) To calender; to press (paper, etc.) between rollers to make it glossy.

Cone➦

Cylinder➦

A solid body which may be generated by the rotation of a parallelogram round one its sides; or a body of rollerlike form, of which the longitudinal section is oblong, and the cross section is circular.

Cone➦

(slang) The process of smoking cannabis in a bong.

Cylinder➦

The revolving square prism carrying the cards in a Jacquard loom.

Cone➦

(slang) A passenger on a cruise ship (so-called by employees after traffic cones, from the need to navigate around them)

Cylinder➦

A cylindrical container for oxygen or compressed air

Cone➦

(category theory) An object V together with an arrow going from V to each object of a diagram such that for any arrow A in the diagram, the pair of arrows from V which subtend A also commute with it. (Then V can be said to be the cone’s vertex and the diagram which the cone subtends can be said to be its base.)

A cone is an object (the apex) and a natural transformation from a constant functor (whose image is the apex of the cone and its identity morphism) to a diagram functor. Its components are projections from the apex to the objects of the diagram and it has a “naturality triangle” for each morphism in the diagram. (A “naturality triangle” is just a naturality square which is degenerate at its apex side.)

Cylinder➦

Cone➦

More generally, any solid having a vertical point and bounded by a surface which is described by a straight line always passing through that vertical point; a solid having a circle for its base and tapering to a point or vertex.
