I was, for a time, able to recite the first 100 numbers of pi of the top of my head. I did this by doing the following:
I split the numbers of pi up in to rows of ten. I have provided an example of the first few numbers:
3.
1415926535
8979323864
2463383279
I just learnt the rows of 10

I am 10 year old and pi is used to find the circuference of a circle. It is used because it is the ratio of the circuference to its diameter more specificly Pi is a rule in mathematics enjoy learning!!
There is no last digit of pi. It is possible to calculate the digits of pi an infinite number of times. The one millionth number is 5.
Aryabhatta did not discover pi - it was known long before him. He found a more accurate value and a method for calculating pi to greater accuracy than was previously known.
Rem4 x 3.14 ember the Circle Equations C = 2 pi r A = pi r^(2) If 'r' (radius) = 2 units then C = 2 pi x 2 = 4 x pi = 4 x 3.14 = 12.56 units. A = pi 2^(2) = 3.14 x 4 = 12.56 units^(2) NB pi = 3.141592.... It is an irrational constant. However, when learning circle equations you are usually given pi = 3.14 , or 3.1416 or 22/7, These are only approximations given for ease of learning.
