Why is March 14th called Pi Day?
Every year on March 14, the world celebrates Pi Day to recognise the mathematical constant, Pi. It defines as the ratio of a circle’s circumference to its diameter and the value for Pi is 3.14. diameter and its value is 3.14. The following number is 14, hence the March 14 date.
Who came up with 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.
How is pi defined?

Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.
Who is the father of pi?
The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
What if Pi wasn’t 3?
If Pi wasn’t 3.1415 and so on, circles wouldn’t exist as we know them today. I also found out there was a mathematician in Indiana who was convinced Pi was actually 3.2. He even tried to make it a law so all the students in the state would have to use that number in their math classes. Of course, it didn’t pass.
When was the number pi first used to denote the number?
It was not until the 18th century — about two millennia after the significance of the number 3.14 was first calculated by Archimedes — that the name “pi” was first used to denote the number. In other words, the Greek letter used to represent the idea was not actually picked by the Ancient Greeks who discovered it.

What is the origin of the Greek letter Pi?
According to Petr Beckmann’s A History of Pi, the Greek letter π was first used for this purpose by William Jones in 1706, probably as an abbreviation of periphery, and became standard mathematical notation roughly 30 years later. Try a brief experiment: Using a compass, draw a circle.
