2*pi is one complete revolution, i.e. 360 degrees. Sin of 2*pi = sin 360º = 0
Circumference of circle: 7.2*pi units or 7.2 * 3.14159265 = 22.6194671 with rounded values for pi and the resulting circumference.
It's a Greek letter. Greek letters are often used to express constants (mathematical values that don't change).
That was William Jones, from England, in 1705
10log10 (p1 /p0 ) where the pi are power values.
i think it was albert Einstein gave pi its symbol but im not sure.
Pi cannot be expressed exactly as any fraction (including as a fraction of powers of 10, which is what a decimal fraction is). There are an infinite number of place values in the number 'pi'.
infinite number of digits after the decimal point -- pi does not have a finite value.
Because pi = 0.5*tau
There are no repeating strings of values in pi.

2*pi is one complete revolution, i.e. 360 degrees. Sin of 2*pi = sin 360º = 0
Cosecant of k*pi radians Secant of 0.5*(2k+1)*pi radiansCotangent of k*pi radianswhere k is an integer.
They gave it a value of about 3 but even today we do not know the exact value of pi
Pi as a mathematical symbol was introduced by William Jones in 1706
They both use pi to determine their values
Every person who has ever used the "value" of pi in a calculation has used an approximation.
