Pi is often written formally as or the Greek letter π as a shortcut. Pi is also an irrational number, meaning it cannot be written as a fraction (), where 'a' and 'b' are integers (whole numbers). This basically means that the digits of pi that are to the right of the decimal go forever without repeating in a pattern, and that it is impossible to w...
Today, there are different ways to calculate many digits of . This is of limited use though. Pi can sometimes be used to work out the area or the circumference of any circle. To find the circumference of a circle, use the formula C (circumference) = π times diameter. To find the area of a circle, use the formula π (radius²). This formula is sometim...

The sample mean of Expression error: Unrecognized punctuation character "'". is μ = 56/5, and so 2(200)μ−2 ≈ 3.19 is within 0.05 of π.- The symbol for Pi has been in use for over 250 years. The symbol was introduced by William Jones, a Welsh mathematician, in 1706. The symbol was made popular by the mathematician Leonhard Euler.
- Since the exact value of pi can never be calculated, we can never find the accurate area or circumference of a circle.
