It was used by the ancient Baylonians over 4000 years agoand in Biblical times whereas at the time it was said to have a value of 3.
But even today we do not know its exact value only that the circumference of any circle divided by its diameter is equal to pi which is an irrational number having decimal places to infinity or without ending.
Pi was known before 1706 but William Jones used the Greek letter for pi in 1706. Euler popularized the use.
The first known people to use the concept of pi were the ancient Babylonians and Egyptians. The Babylonians approximated pi as 3.125 around 1900 BCE, while the Egyptians used a value of approximately 3.16 in their calculations, as evidenced in the Rhind Mathematical Papyrus. These early civilizations utilized pi in their geometry, particularly in relation to circles.
the number is that you use for pi is 3.14 the number is that you use for pi is 3.14
Just divide 56 by pi. Pi is approximate 3.14; or use the "pi" key on your scientific calculator.Just divide 56 by pi.

Circumference = 2*pi*radius So the radius = circumference/2*pi
Use the formula A = pi x r2 (area = pi x radius2). Replace the known area, and solve for radius. (Use only the positive solution.)
If the radius is known, use this formula: V = 4/3(PI*r3)
The longest known value of pi is now into the hundreds of billions of digits.

No. pi was known long before.
the founder of the longest pi is...
people use pi to find the circumference of a circle.
