Question

what history tells about 'pie' = 22/7?​

Answer 1

Approximations for the mathematical constant pi (π) in the history of mathematics reached an accuracy within 0.04% of the true value before the beginning of the Common Era (Archimedes). In Chinese mathematics, this was improved to approximations correct to what corresponds to about seven decimal digits by the 5th century.

Further progress was not made until the 15th century (Jamshīd al-Kāshī). Early modern mathematicians reached an accuracy of 35 digits by the beginning of the 17th century (Ludolph van Ceulen), and 126 digits by the 19th century (Jurij Vega), surpassing the accuracy required for any conceivable application outside of pure mathematics.

Answer 2

Answer:

Pie is an Greek alphabet used for creating the accurate circle and the perfect circle diamater was 7 and it's circumference was 22 the first mathematical formula was created from 22/7 and it's notation was the letter pie.
