What does the symbol "π" approximately equal?

The symbol "π" (pi) is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. Its approximate value is 3.14, which is often used in calculations involving circles, such as finding the area or circumference. This value is widely recognized and is an essential concept in geometry and trigonometry. The significance of π extends beyond just its numerical approximation; it is an irrational number, meaning it has an infinite number of non-repeating decimal places. The approximation of 3.14 is commonly used in educational settings for simplicity, allowing students to perform calculations without requiring the entire decimal representation of π.
