The value of π (pi) is commonly approximated as 3.14, which is used frequently in educational contexts and practical applications to provide a simple yet effective representation of this mathematical constant. Pi is defined as the ratio of a circle's circumference to its diameter and is an irrational number, meaning it has an infinite number of non-repeating decimals. While the more precise value of pi extends far beyond 3.14, this approximation is particularly convenient for basic calculations in geometry and trigonometry, making it a staple in mathematical education and practical problem-solving scenarios. It represents a balance between simplicity and adequate accuracy for many applications.
