What is the name of a part of a region between concentric circles?
$begingroup$
I am wondering what the name for a section of the area between two concentric circles is called? It's essentially an isosceles trapezoid with the "parallel" sides now curved. I have Googled different iterations of "rounded trapezoid" and "2D toroidal section" etc., but have not found a term that I feel suits this shape.
I appreciate everyone's help.

I don't think it has a known name. If you need one for something you are writing, make one up and tell your reader. "Angular section of an annulus" might do.

Yes, I'm writing an academic journal paper and some of these terms are out of my wheelhouse. I appreciate the recommendation of defining my term for the reader. I just want to make sure I'm not making up a name for it if a name already exists. Imagine dancing around the word "triangle", haha.

Such a shape is sometimes referred to as a truncated sector or an annular sector. Here is a link to google search results showing the use of the term "truncated sector."

In some contexts it's also called a "Polar Rectangle" since it is the region $(r_0 leq r leq r_1) times (theta_0 leq theta leq theta_1)$. That is, it's the product of two polar intervals.

The area between two concentric circles is called: an annulus.
So you can call the blue part: a sector of an annulus.
