Figurate / Polygonal Number Question : I recently saw the posts on 'reversing figurate number' evaluations at these links on the forum here ; Figurate numbers  deriving backwards  Physics and Mathematics  Science Forums Polygonal Numbers  Backwards Derivations  Physics and Mathematics  Science Forums QUESTION : I'd like to be able to find the diameter of any 2d or 3d polygonal, figurate number with 3,4,5, or more sides  based on the figurate number being comprised of circles that have a diameter of 1 inch each. Id like to be able to describe this with a simple formula that I can use for any shaped polygonal number, so for example I could apply this to a square number or a cube number, a pentagonal number, etc... I think the total circle area would play a part in this? Any insights and or meaningful feedback, especially tips on how to construct such a formula would be greatly appreciated! Thank you! A
