Question from gigi, a student: What value of pi did the indians use? |
Hi Gigi,
In ancient times, the Indians approximated pi to be about the square root of 10. The Indian mathematician and astronomer Aryabhata in the 5th century gave the approximation of pi = 62832/20000 = 3.1416, which is even more accurate.

Hi Gigi,
At the The MacTutor History of Mathematics archive there is a page called History Topics: Index of Ancient Indian mathematics. On this page there is a note called History of Pi and another, Chronology of Pi. These are interesting reading.
