Is pi a real numbers?
Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666…). (To only 18 decimal places, pi is 3.141592653589793238.)
Why is Pi Day so special?
It is a day to celebrate the mathematical constant pi (π) and to eat lots of pie. It is celebrated in countries that follow the month/day (m/dd) date format, because the digits in the date, March 14 or 3/14, are the first three digits of π (3.14). Pi Day was founded by Physicist Larry Shaw in 1988.
Who first calculated pi?
Archimedes of Syracuse
The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
What does the symbol pi mean?
π
The symbol used by mathematicians to represent the ratio of a circle’s circumference to its diameter is the lowercase Greek letter π, sometimes spelled out as pi, and derived from the first letter of the Greek word perimetros, meaning circumference.

Why is pi 22 divided 7?
It is known that pi is an irrational number which means that the digits after the decimal point are never-ending and being a non-terminating value. Therefore, 22/7 is used for everyday calculations. ‘π’ is not equal to the ratio of any two number, which makes it an irrational number.
Who found pi?
The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
Will pi ever end?
Technically no, though no one has ever been able to find a true end to the number. It’s actually considered an “irrational” number, because it keeps going in a way that we can’t quite calculate. Pi dates back to 250 BCE by a Greek mathematician Archimedes, who used polygons to determine the circumference.
How did we figure out pi?
The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
