314159
3.14159*105
If you mean 314159 then it is a prime number
Given a circle with an area of 314,159; find the radius r. The area of a circle is determined by the formula π * r2 A = πr2 Because we have a value for A, we substitute 314159 = πr2 We have to get r on one side of the equation, by itself. To do this, divide both sides by π. ( 314159 / π ) = πr2 / π Simplify ( 314159 / π ) = r2 We need r to be the only thing on it's side of the equation, so we'll take the square root of both sides, and simplify. sqrt( 314159/π ) = r This answer is correct, but because we had a value for A, we can get a decimal approximation. r = sqrt ( 314159 / 3.14159 ) r = sqrt ( 100,000) r = 316.227766

It is a rational number - a ratio of two integers - that is sufficiently close to an irrational number so as to be used instead. Calculators and computers- unless using double precision - usually store irrational numbers to 16 digits. In schools, for example, pi is often approximated by 22/7. Later on 3.142 ( = 3142/1000) or 3.14159 ( = 314159/100000) may be used. Yet another ratio, which is accurate to 7 digits, but is not used much, is 355/113.
The number 3.14159 can be expressed as a fraction by understanding that it is the decimal representation of the mathematical constant pi, which is the ratio of a circle's circumference to its diameter. Pi is an irrational number, meaning it cannot be expressed as a simple fraction. However, it is commonly approximated as 22/7 in fraction form, which is accurate to a reasonable degree for most practical purposes.
