The true value of pi is equal to the circumference of a circle divided by it's diameter. This value can not be expressed numerically, because it's an irrational number. The first few digits however, are:

If you mean "the value of pi rounded to the nearest hundredth," then: 3.14
Suppose you want to calculate the area of a circle with a radius of 10 cm.If you use pi = 3.14 the area will be calculated as 314 cm^2if, instead, you use pi = 3.145159, the area will be 314.5159 cm^2if you use pi, as used by Excel on my computer, you will get 314.159265358979 cm^2.If you use the most accurate value of pi (currently around 10 trillion digits) you will get a more accurate value of the area.The difference between the calculated value and the true value is the truncation value.
The longest known value of pi is now into the hundreds of billions of digits.
