65.537-gono

Zirkunferentzia zirkunskribatuaren erradioaren luzera ${\displaystyle r}$ bada:

• Aldea: ${\displaystyle l=2\cdot r\cdot \sin \left({\frac {1}{2}}\cdot {\frac {2\pi }{65.537}}\right)\simeq r\cdot 0{,}00009587}$
• Azalera: ${\displaystyle A=65.537\cdot r^{2}\cdot \sin \left({\frac {180^{\circ }}{65.537}}\right)\cdot \cos \left({\frac {180^{\circ }}{65.537}}\right)\simeq 3{,}141592649\cdot r^{2}}$
• Perimetroa: ${\displaystyle P=65.537\cdot l\simeq r\cdot 6{,}2831853}$
• Barne-angelua:${\displaystyle \beta =\pi -{\frac {2\pi }{65.537}}=180^{\circ }-{\frac {360^{\circ }}{65.537}}\simeq 179{,}9945^{\circ }}$
