Pi, denoted by the symbol π, is a mathematical constant that represents the ratio of a circle's circumference to its diameter. In other words, it's the number you get when you divide the distance around a circle by its width. Pi is an irrational number, meaning that it cannot be expressed as a simple fraction or a finite decimal.
The value of pi is approximately 3.14159, but it continues infinitely without any repeating pattern. It is commonly rounded to 3.14 or 22/7 for simplicity in calculations. However, if you require a more precise value, you can use a calculator or refer to pi to a greater number of decimal places, such as 3.14159265358979323846.
