Agulha de Buffon e o número Pi

Lolu hlelo lokusebenza luhlanganisa ukuhlolwa kwezibalo okwaziwa ngokuthi inaliti ye-Buffon. Kuyinkinga yamathuba ejiyomethri yakudala, lapho inaliti iwelwa ngokungahleliwe endaweni yemigqa ehambisanayo ehlukaniswe ngokulinganayo. Lolu hlelo lokusebenza lulingisa ikesi elilula lapho ubude benaliti buyibanga phakathi kwemigqa emibili ehambisanayo. U-N mayibe ingqikithi yenali lezinaliti eziphonswe ngesikhathi esinikeziwe; ake C kube inombolo izinaliti ukweqa imigqa. Vumela u-R = 2 × N ÷ C. R ukulinganisa kwe-Pi ( π). Kulolu hlelo lokusebenza, umsebenzisi angashintsha inombolo yezinaliti eziwiswe kumpompi ngamunye kanye nenani lezintambo endaweni eqondiwe.
