What is the most accurate fraction for pi?

Pi, being irrational, has an endless number of digits to the right of the decimal, as you know. But for almost any application, even basic engineering, a value of 3.1417 is highly accurate.


What is the formula to figure out the area of a circle with pi being 3.14?

Area = pi * radius squared A = pi * r2 Best to use the calculator value of pi to 9 places for more accurate answers.


Why is it not possible to work out the accurate area of a circle when given its diameter?

The formula for the area of a circle is pi times the radius squared. The number pi is only used in an approximate form, since the decimal expansion of pi is infinitely long and non-repeating. Consequently, all calculations of the area of a circle are also approximate. However, you can be as accurate as you want to be. Pi has been calculated to thousands of decimal places, which is ridiculously more than you would ever need for any practical purpose. In most cases, the approximation of pi as 3.14 is close enough. Your result will be accurate, it just won't be 100% accurate.

Why mathematics call 3.14 pi?

Well, 3.14 isn't really accurate pi. pi is the value when circumference of the circle is divided by it's radius. It makes easier to estimate the length of circumference of the circle. Pi = 3.141592..............(infinite)
