What is the approximate value of π?

The value of π, or pi, is a fundamental mathematical constant representing the ratio of a circle's circumference to its diameter. This ratio is approximately equal to 3.14, which is often used for practical calculations. This value is crucial in a multitude of mathematical and engineering applications, including calculations involving circles and circular shapes, such as those commonly encountered in septic systems.

The other options present values that are significantly different from the actual value of π, making them unsuitable for accurate mathematical work related to geometry or physics. Thus, understanding that π is approximately 3.14 is essential for anyone working in fields that require geometric calculations, including those in the septic industry.
