No one because the exact value of pi in circle has never been determined and it is an irrational number.

the fraction 22/7 is often used as an approximation for the value of pi. it is off from the actual value by about 0.04 percent (1 in 2500). This would be like measuring a football field and being off by about 1.5 inches on your measurement. The fraction 355/113 is amazingly close, better than 1 part in 10 million
Suppose a sine wave of the form y = A*sin(k) withA = amplitude or maximum value of the function y (namely when k = pi/2 or 90°)k = the value on the x-axis of the functionIt's typical of a sine wave that it's periodic, which means the function y repeats itself after a certain period. This period is equal to 2*pi or 360°, for example:for k = pi/2, 5*pi/2, 9*pi/2, ... the value of y will be the same and equal to A (notice that 5*pi/2 = pi/2 + 2*pi and 9*pi/2 = 5*pi/2 + 2*pi)In physics it's a more common practice to write a sine wave as y = A*sin(omega*t) with omega the angular frequency specified in radians/s (omega refers to the Greek letter) and t the time specified in seconds.Now, when you want to calculate the frequency f of a sine wave (which is not equal to the angular frequency) or in other words the number of complete cycles that occur per second (specified in cycle/s or s-1 or Hz), you need to know the time T required to complete one full cycle (specified in s/cycle or just s or Hz-1). The frequency f is then equal to 1/T.Knowing omega you can calculate the frequency in a different and more common way:since the sine wave is periodic and after a time T one cycle has been completed (thus one period), it follows that omega*T = 2*pi for the function y to have the same value after one period (the function y having the same value is equal to completing one cycle).Let's rearrange this formula by bringing 2*pi to the left and T to the right, so we get:omega/(2*pi) = 1/T and since 1/T = f we finally get:f = omega / (2*pi)
There are unlimited digits in pi and they never repeat. The first few are 3.14159.......
In any circle, the product of pi and the diameter will be the circumference. That is because pi is the ratio of the diameter of a circle to its circumference. Here is the equation: c = pi x d
pi IS real. It's irrational, but not unreal.

the founder of the longest pi is...
The first to find the value in pi were the Babylonians and Egyptians.
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 value of Pi is 3.14159, but the first 10 digits are 3.141592658
Archimedes (287-212 BC) was the first to have had a serious attempt at calculating pi.
People from ancient civilizations knew about the value of pi but as it was then as it is now the exact value of pi has never been conclusively found because it is an irrational number.
No, the value of pi was not first calculated by Budhayana. It is debated who the first person was to calculate it. However, it is believed that Archimedes was the first to calculate it using polygons, while Ptolemy was the first to assigned it its current value directly.

The first person to use pi is the awesome man Archimedes he was the first to compute pi's value accurately! I know this answer and I'm in 5th grade!:)
Here are the first 100 digits in Pi.3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679Thank y'all for reading
