To get pi (π), you divide a circle's circumference by its diameter.
Pi (π) is defined as the ratio of a circle's circumference to its diameter. This ratio is a constant number, approximately equal to 3.14159. Regardless of the size of the circle, this ratio remains the same. Therefore, to arrive at the value of pi, you perform the division:
- Circumference / Diameter = π
For example, if a circle has a circumference of 6.28318 units and a diameter of 2 units, then 6.28318 / 2 ≈ 3.14159, which is approximately pi. Pi is an irrational number, meaning it cannot be expressed as a simple fraction of two integers. A common approximation of pi is 22/7, but this is not its exact value.
