An “approximate number of pi” refers to a numerical value that closely represents the mathematical constant pi (), which is the ratio of a circle’s circumference to its diameter. For instance, the approximation of 22/7 is commonly used to estimate pi.
Determining an accurate approximation of pi is crucial in various fields, including engineering, mathematics, and physics. It allows for precise calculations and has practical applications in navigation, construction, and computer science. A notable historical development was Archimedes’ method of exhaustion, which provided an early approximation of pi as 3.14.
