About Pi Formula

The circumference and diameter of a circle are calculated using the Pi formula. If the circumference and diameter of a circle are given, it can be used to compute the value of pi. Pi is a Greek letter with the symbol, and it is the ratio of the circumference of a circle to its diameter in geometry. The value of pi in decimal form is about 3.14159... It's impossible to write as a precise decimal since the digits continue on indefinitely. Let's look at the pi formula and solve a few cases at the end.

What is Pi Formula?

Pi cannot be stated as a common fraction since it is an irrational number. Although fractions like 22/7 are usually used to approximate it, the pi formula can be used to get the actual value of pi, which is a non-terminating non-repeating decimal. The circumference divided by the diameter of a circle, no matter how great or little, is always. The Pi formula is written as,

Pi (π) formula = (Circumference / Diameter)
