What is the approximate value of pi?

The approximate value of pi is commonly known to be 3.14. Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. It is an irrational number, meaning that it cannot be expressed as a simple fraction, and its decimal representation goes on forever without repeating.

In many mathematical calculations, 3.14 is used as a simple approximation for pi, making it easier to work with, especially in basic geometry and trigonometry. This value allows students and practitioners to perform circle-related calculations with a reasonable degree of accuracy for everyday applications.

While there are many other approximations for pi, such as 22/7 or 3.14159, 3.14 is the most frequently used in basic mathematics and education settings because it is easy to remember and sufficient for many practical purposes.
