Pi the full number is a mathematical constant, often represented by the Greek letter ‘pi’ (). Defined as the ratio of a circle’s circumference to its diameter, its decimal representation is an infinite, non-repeating sequence. For instance, approximating pi as 3.14 gives us a practical understanding of its value when calculating a circle’s area or circumference.
Pi holds significant importance in mathematics, physics, engineering, and other disciplines. It enables precise calculations, measurements, and predictions. Historically, Archimedes played a pivotal role in its early development, devising methods to approximate pi’s value.
