Qeybta hoose ka dibna ka jawaab su'aasha kadib isla luqadda sida marinka: Marinka: In Shiinaha qadiimiga ah, qiimaha π waxaa ka mid ah 3.1547 (qiyaastii 1 AD), √10 (100 AD, qiyaastii 3.1623), iyo 142/45 (qarnigii 3aad, qiyaastii 3.1556). Qiyaastii 265 AD, Wei Kingdom xisaabiye Liu Hui abuuray polygon-ku salaysan algorithm iterative oo loo isticmaalo polygon 3,072-dhinac ah si loo helo qiimaha π of 3.1416. Liu ka dib abuurtay hab dhakhso ah ee lagu xisaabiyo π iyo helay qiimaha 3.14 la polygon 96-dhinac ah, iyadoo ka faa'iidaysanaya xaqiiqda ah in farqiga aagga of polygons isku xigta sameeyaan taxane joomatari la factor of 4.
