The circumference of a circle when divided by its diameter is the value of pi which is an irrational number that can't be expressed as an exact fraction.
Historically, Ancient Egyptians are the first who introduced a reasonably accurate value for the ratio of the circle area and its square radius. They used an approximate value of 3.1605 for pi The ancient Babylonians generally calculated the area of a circle by taking 3 times the square of its radius (=3), but one Old Babylonian tablet (from ca. 1900-1680 BD) indicates a value of 3.125 for pi. The first theoretical calculation of a value of pi was that of Archimedes of Syracuse (287-212 BD), one of the most brilliant mathematicians of the ancient world. Archimedes worked out that 223/71 < pi < 22/7 The Greek letter π (pi) was adopted for the number from the Greek word for perimeter "περίμετρος", first by William Jones in 1707, and later popularized by Leonhard Euler in 1737. The constant is occasionally also referred to as the circular constant or Archimedes' constant.

There is no recorded single discoverer of the value of pi. Although, it has been recorded that the Egyptians were aware of pi.
Archimedes
The ancient Babylonians from around 1700 BC used pi = 3.125. The name of the person who calculated that value was not recorded.
The ancient Babylonians were one of the first who gave it a value of about 3 but even today we do not know the exact value of pi only that a circle's circumference dividedby its diameter is equal to pi which is an irrational number because it cannot be expressed as a fraction.

3.14 or 22/7 and the definition is A transcendental number, approximately 3.14159, represented by the symbol π, that expresses the ratio of the circumference to the diameter of a circle and appears as a constant in many mathematical expressions. The first theoretical calculation of a value of pi was that of Archimedes of Syracuse (287-212 BCE), one of the most brilliant mathematicians of the ancient world. Archimedes worked out that 223/71 < pi < 22/7.
Every person who has ever used the "value" of pi in a calculation has used an approximation.

The circumference of a circle can be calculated by multiplying pi by the diameter of the circle. For example if the diameter is 10 then the calculation will be pi x 10 = answer. The most commonly used value for pi is 3.14
