Dear All
On the occasion of World Pi Approximation Day being celebrated on 22nd July (22/7), here is a very interesting Quiz to know about Pi.
Don't forget to share with your known/students/teachers/
Just give a TRY
The story of pi is more than 4000 years old but the race to find its value is still continued.
Interesting Facts:-
1. NASA notes only 37 digits of π are needed to calculate the circumference of the observable universe to hydrogen-atom precision, so these records are more about data management and computational endurance than practical necessity.
2. Official world record (June 2026) to calculate the value of pi is now 340 trillionth digits
4. 14th March 1879 is the birthday of Albert Einstein whereas Stephan Hawking died on 14th March 2018. It is interestingly the birthday of WacLlaw Sierpinski who is known for Sierpinski triangle and square.

A brief Introduction of Pi
Value of Pi = 22/7 is probably taken because Archimedes (born in 287 BC) calculated the ratio of circumference to diameter coming out to be lying between 223/71 and 22/7.
Aryabhata (born in 476AD) was the first Indian mathematician who calculated the value of pi correct up to 4 decimal places. His value of pi was 3.1416.
The Mahabharta decodes the value of pi as 3.

The Moon is handed down by memory to be eleven thousand yojanas in diameter. Its peripheral circle happens to be thirty three thousand yojanas when calculated.
The Sun is eight thousand yojanas and another two thousand yojanas in diameter. From that its peripheral circle comes to be equal to thirty thousand yojanas.
The Bible says -
Also he made a molten sea of ten cubits from brim to brim round in compass and five cubits the height thereof; and a line of thirty cubits and compass it round about. --- Old Testament
William L Schoff says -
Probably no symbol in mathematics has evolved much mystery, romanticism, misconception and human interest as the number of pi.
In 1901, Italian
mathematician Mario Lazzarini Performed the Buffon Needle experiment tossing a
needle 3408 times, he obtained the approximation of pi which was a very
accurate value.
