Formulas for the regular polygon ring
Perimeter (\(\small{P}\))
\(\displaystyle P = (a + b) · n \)
Area (\(\small{A}\))
\(\displaystyle A = \frac{n·(a^2-b^2)}{4·\displaystyle tan\left(\frac{π}{n}\right)} \)
Thickness at vertices (\(\small{c}\))
\(\displaystyle c = \frac{a-b}{2·\displaystyle sin\left(\frac{π}{n}\right)} \)
Thickness at edges (\(\small{c}\))
\(\displaystyle d = \frac{a-b}{2·\displaystyle tan\left(\frac{π}{n}\right)} \)
