What is the name for the section of a flat ring (annulus)? Similar to a section on a radar screen, a quadrilateral but the top and bottom are curved. |
Ed,
I don't think it has any special name. While I would write "sector" rather than "section", I would call it an "annular sector" or "sector of an annulus".
Good Hunting!
