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.
