Possible topic for publication on Community

This topic is more of pure mathematics, but all calculations are done on Mathematica
so I put it here.
One day the question arose: how to determine centroid of annulus to be in the specified place?

Of course, it can’t be usual centroid as a mass center. We can use symmetry, radius and concentric circle for geometric definition.
But this is not suitable for more general cases:

This led me to investigate the question of the types of centroids of shapes,
which produced interesting results.
In particular, a simple definition for the specified center was found:

The point that minimizes the difference between maximum and minimum distance (inside figure)
to the boundary

The analysis was conducted on Mathematica 13 using DiscretizeRegion and MeshConnectivityGraph
I have not yet published contributions for Wolfram Community and would like to ask:

  • Perhaps someone has met the above definition (in more detail on stackexchange)
  • In any case, would it be useful to publish in 3-4 groups a small study of this subject using cool Mathematica features?

I see no reason not to post, if code is provided.

Thank you for encouragement!
I’m interested, is it possible to use in posts interactive cells,
or only results and images?

If you add a notebook file to the post using the “Add a file to this post” button then interactive content will be rendered in the browser as long as it is not too complex or resource-intensive to render. It can be downloaded and evaluated in a local Mathematica installation by anyone who wants to reproduce the computations locally.
