The value of pi using everywhere small unit measure of electron and a large unit of galaxies planets as well as the whole universe.

In mathematics, pi is most useful in the circle in geometry

we can't imagine mathematics without pi.

To find volume and area of circular object need pi.





Aryabhatta already had discovered the value of pi.





चतुरधिकं शतमष्टगुणं द्वाषष्टिस्तथा सहस्राणाम् । श्रप्रयुतद्वयविष्कम्भ स्यासन्नो वृत्तपरिणाहः ( आर्यभटीय गणितपाद श्लोक १०)





It means





Add four in hundred, then multiply by eight and add sixty-two thousand.

It's the value of Circumference which has twenty thousand diameters.





Its is clearly told that





Circumference = ((100+4)*8)+62000 = 62832







we know the formula Circumference = 2πr ( r= d/2)

or, 62832 = 2* π*20000/2





or, π = 62832/20000





or, π = 3.1416





which is the

Approximate Measure of pi





Great Mathematician Aryabhatta was already told about pi,

and also the formula of Circumference

because there was clearly explained about Circumference and

this measure is fit with the value of pi and formula of Circumference
