Meaning and Definition
A three-dimensional geometric solid consisting of two parallel circular bases of equal size connected by a curved lateral surface that is perpendicular to the bases.
In broader technical contexts, the most fundamental and symmetric form of a cylinder, often used as a standard shape for calculations in engineering, fluid dynamics, and manufacturing. Its properties define the default 'cylinder' in many mathematical and scientific discussions.

Common Mistakes When Using “right circular cylinder”
- Saying 'round cylinder' – 'circular' is the precise geometric term.
- Using 'cylinder' alone when the 'right' and 'circular' properties are crucial to the problem.
- Confusing the height with the slant height (which is only relevant for oblique cylinders).
FAQ
Frequently Asked Questions
In theory, they are designed to be very close approximations. In practice, manufacturing imperfections mean they are not geometrically perfect right circular cylinders.
'Cylinder' is a general term for any solid with parallel congruent bases connected by a lateral surface. 'Right circular cylinder' is the most specific and common type, where the bases are circles and the sides are perpendicular to them.
In geometry, 'right' indicates a 90-degree angle. Here, it means the line joining the centres of the bases (the axis) is at a right angle (perpendicular) to the planes containing the bases.
Yes. The term describes the shape's geometry, not its solidity. A hollow right circular cylinder is often called a cylindrical shell.
A three-dimensional geometric solid consisting of two parallel circular bases of equal size connected by a curved lateral surface that is perpendicular to the bases.
Right circular cylinder is usually academic / technical in register.
Right circular cylinder: in British English it is pronounced /ˌraɪt ˌsɜː.kjə.lə ˈsɪl.ɪn.dər/, and in American English it is pronounced /ˌraɪt ˌsɝː.kjə.lɚ ˈsɪl.ɪn.dɚ/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Imagine a soup can. The label is a rectangle wrapped around perfectly straight (RIGHT), and both the top and bottom are perfect circles (CIRCULAR). That's your Right Circular Cylinder.
Conceptual Metaphor
ARCHETYPE OF SYMMETRY: The right circular cylinder serves as the mental prototype for the entire category of 'cylinders', against which other variants (oblique, elliptic) are compared.
