Who is the founder of pi in math?

Answer 1

Pi is a letter in the Greek alphabet but it is the ratio of the circumference to the diameter of a circle. Approximately 3.142 (at 3 decimal places).

Earliest references to Pi was by the Egyptians, who calculated it to be approximately (4/3)^4 which equals 3.1604.

Generally, Archimedes of Syracuse is considered to be the main man. He found that pi is somewhere about 3.14 (in fractions; Greeks did not have decimals).

New knowledge of Pi then bogged down until the 17th century. Pi was then called the Ludolphian number, after Ludolph van Ceulen, a German mathematician. The first person to use the Greek letter Pi for the number was William Jones, a Welsh mathematician born in the village of LLanfihangel in Anglesey, who coined it in1706.
