How to calculate PI value?
If you mean “pi”, then it is circumference/ diameter. Just take a circle (soda can top, etc.), take a string and measure around the top of can and straight across the top. You will need to use a ruler to measure what you just measured. Divide your circumference you found by the diameter you found, and you will get the special number,” pi”. That number is a consistent answer no matter what the circumference and diameter is, provided these both come from same circle.
Pi or π is the ratio of a circle’s circumference to its diameter. There are several methods to calculate it. You can actually measure the circumference and diameter of a big circle and divide circumference with diameter to get the value of π. When the circle is bigger you get more accurate result. The value of π can be calculated by mathematical methods which give more accurate results. Since π is an irrational number you can not write its numerical value. In a calculator you can get its value like 3.1415926535897932384626433832795, but it is only an approximate value only. But value of π with 10 digit accuracy is OK for almost all practical applications. Visit the following link for more details.
