Right circular hollow cylinder

 * – ( View AfD View log  Stats )

Not notable. Specifically: The subject is a specific example of the use of the formula for a cylinder, using simple arithmetic. If this subject should be anywhere in Wikipedia, it should be a small part of the article Cylinder (geometry). Anita5192 (talk) 20:07, 25 September 2016 (UTC)
 * Subject is notable and topic notable too. As in cubes,cuboid,prisms,cones and pyramids etc. only formula are used for calculation similarly formula are used in cylinder ,right circular hollow cylinder,hemisphere,sphere etc.
 * More utility of hollow cylinder is found in daily life in comparison of cylinder,more utility  is found in various machines,irrigation,engineering etc.
 * cube and cuboid are separate articles with minor difference
 * cuboid and parallelepiped are separate articles having with minor difference.
 * tetrahedron and cube are separate articles with minor difference.
 * Why not cylinder and Right circular hollow cylinder are separate articles?Nagric (talk) 03:56, 26 September 2016 (UTC)Teacher1943

KeepIs cube,cuboid,prism,pyramid ,sphere,cone are not elementary topic,why are these topics are separate ? Please do not say elementary topic. Without Right circular hollow cylinder solid geometry will be incomplete.Nagric (talk) 16:19, 26 September 2016 (UTC)
 * Delete. Wikipedia is WP:NOTTEXTBOOK, especially for so elementary a topic. Clarityfiend (talk) 07:53, 26 September 2016 (UTC)

 * Comment, is there any reason why this can't be merged with Cylinder (geometry) appearing under Other types of cylinders?, as for other "elementary topics" being separate, merge discussions can be started on their respective talkpages if editors think WP:OTHERSTUFF.

 Relisted to generate a more thorough discussion and clearer consensus.
 * Delete: As per Clarityfriend above. This does not add anything of mathematical value; it does not say anything of engineering value either (there could be stuff about calculating the internal volume of a cylinder made from a rectangle of sheet metal of a certain thickness, but none of this is notable, it is just elementary calculations on more or less arbitrary shapes.

 * delete a trivial construction from two cylinders, not notable in its own right.-- JohnBlackburne wordsdeeds 23:54, 1 October 2016 (UTC)
 * Keep Google books shows that the snippet for Space Power Systems reads, "The shape of the fuel--a right circular hollow cylinder--was arrived at as a compromise between heat transfer and mechanical or fabrication concerns. It is desirable to place the fuel at the end of the heat source close to the area where surplus..."  This article is far from trivial, requiring the math to understand the object being described, as the object includes the volume between the two cylindrical shells, but not the volume in the central core.  The idea that there is any justification for not covering this topic in the encyclopedia I can't imagine.  Definitions appear to be needed for orthotropic right circular hollow cylinder and isotropic right circular hollow cylinder.  There may also be room to add discussion of "The resonant frequency νn of an evacuated right circular hollow cylinder...", as this is mentioned in more than one source.

 * Merge and redirect to Cylinder (geometry) seems the most sensible option. Polyamorph (talk) 12:03, 7 October 2016 (UTC)
 * Redirect as above and perhaps selectively merge, trivial subtopic.  Sandstein   08:45, 11 October 2016 (UTC)
 * Delete. It pains me to say this, because we should have more math articles.  But, as I look at this article, and look at Cylinder (geometry) to see if it makes sense to merge, I just can't see it.  This really is a trivial topic.  There's nothing fundamental about a cylinder with a hole down the middle.  The formulae for surface area and volume of this shape are straight-forward application of the general rules for building complex shapes composed of simpler ones.  -- RoySmith (talk) 00:11, 12 October 2016 (UTC)
