Why is 3.14 called pi? Who came up with 3.14 pi?

The concept of pi dates back thousands of years, with early approximations made by ancient civilizations like the Egyptians and Babylonians. However, the Greek mathematician Archimedes is credited with one of the earliest and more accurate approximations of pi in the 3rd century BCE. The number 3.14, commonly referred to as “pi,” represents the ratio of a circle’s circumference to its diameter.

Answer: The name “pi” originated from the Greek word “π”, which is the first letter of the Greek word “periferia,” meaning “perimeter” or “circumference.” It was first used by the Welsh mathematician William Jones in 1706

It became popular after it was adopted by the Swiss mathematician Leonhard Euler in the 18th century.

Pi is an irrational number, meaning it cannot be expressed as a simple fraction, and its decimal representation goes on infinitely without repeating. Its value is approximately 3.14159265359… and so on.
