What is the approximate value of Pi used in calculations?

The value of Pi, commonly represented by the symbol π, is a mathematical constant that represents the ratio of a circle's circumference to its diameter. In calculations, Pi is typically approximated as 3.14, which is widely recognized and accepted for many practical applications, especially in educational settings.

Using 3.14 provides a sufficient degree of accuracy for various calculations involving circles, such as finding the area or circumference. While Pi is actually an irrational number with a value of approximately 3.14159, rounding it to 3.14 is standard practice when a simpler approximation is needed.

The other options—3.16, 2.14, and 3.00—do not reflect the recognized approximation of Pi, making them less useful for standard calculations involving circular measurements.
