As time went on other people were able come up with better approximations for Pi. About 150 AD, Ptolemy of Alexandria (Egypt) gave its value as 377/120 and in about 500 AD the Chinese Tsu Ch'ung-Chi gave the value as 355/113. These are correct to 3 and 6 decimal places respectively.

By this rule the relation of the circumference to diameter is given." In other words (4+100)×8 + 62000 is the circumference of a circle with diameter 20000. This provides a value of pi = 62832/20000 = 3.1416, ... The Chinese mathematician and astronomer Zu Chongzhi in the 5th century computed pi between 3.1415926 and 3.1415927,

Chinese mathematicians Liu Hui inscribed a 192-sided polygon and then a 3,072-sided polygon to calculate pi to 3.14159. Tsu Ch’ung and his son inscribed polygons with as many as 24,576 sides to calculate pi (the result had only an 8-millionth of 1% difference from the now accepted value of pi).f ...
