It never was and they never were because even today no one has discovered the exact value of pi.
All the ancients knew about pi is what we know today and that is the circumference of any circle divided by its diameter is equal to pi which is an irrational number whose decimal places are infinite.
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
The ancient Babylonians from around 1700 BC used pi = 3.125. The name of the person who calculated that value was not recorded.
I truly do not know. I am truly sorry. It might help if you Google that.
Dividing the circumference by 2*pi will give the value of the radius.
They gave it a value of about 3 but even today we do not know the exact value of pi
PI stands for polarization index. We need to find IR value(IR1) for 1min and again find the IR value(IR2) for 10min. PI=IR2/IR1
In 499ce, he is in 23rd years old .he will find out the approximation of pi
There is no recorded single discoverer of the value of pi. Although, it has been recorded that the Egyptians were aware of pi.
3.14159..... Thomas Jefferson he is a very smart person
You cannot find the "PI" of anything Pi is a set numerical value, PI = 3.14159265358979323846… (It goes on forever) But in geometry we consider Pi to equal 3.14
To find the diameter of a circle divide its circumference by pi
They put the value of pi as about 3 but even today we do not know its exact value only that the circumference of a circle divided by its diameter is equal to pi
