Why the value of 'pie' is taken as 22/7?
It isn't.
A pie's value is as a very tasty dessert.
The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi" (/paɪ/).
The above three posts are bogus and not from the real Ms. Sue.
The value of 'pi' (π) is not exactly equal to 22/7. The precise value of π is an irrational number, which means it cannot be expressed as a fraction or a finite decimal. It is approximately equal to 3.14159... and the decimal representation goes on indefinitely without repeating.
The approximation of π as 22/7 is commonly used because it is a simple and easy-to-remember value. The fraction 22/7 is a close approximation to the value of π, but it is not completely accurate. When calculations or measurements require greater precision, the actual value of π is used.
To obtain a more precise value of π, mathematicians have developed various methods and formulas. One well-known method is using the Leibniz formula for π, which states that π/4 can be calculated as the sum of an infinite series: 1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 + ...
More advanced methods, such as the Bailey-Borwein-Plouffe formula or the Machin's formula, have been developed to calculate π to millions or even billions of decimal places. These advanced methods utilize mathematical concepts and algorithms to obtain highly accurate approximations of π.
