Answer:
Pi (π) is a mathematical constant representing the ratio of a circle's circumference to its diameter. It is an irrational number, meaning it cannot be expressed as a simple fraction, and its decimal representation goes on indefinitely without repeating. The value of pi is approximately 3.14159, but it is commonly rounded to 3.14 for most calculations. It's an essential constant in many areas of mathematics, physics, engineering, and other scientific fields.
