39 decimal places.
A Precision Number is the number of digits in a number.
the precision of the answer must have the same number of significant digits as the measurement with the least significant digits- the site explains the rules and how to identify significant digits
The significant digits of a number represent a count of digits and so are represented by an integer. Any integer can be written in fractional form.
The answer is limited to the number with the fewest digits of precision (digits after the decimal point). (2 digits of precision)
No, it is not true. They reflect the precision of the number in the context of its use. If required to calculate the population density of Greater London in 2011, I would use the population in millions - not because that is the limit of the accuracy of the census results but because greater accuracy does not add significant value to the precision of the population density.
you only need 3.14 for the circumfrence of a circle

My guess is fewer than 100.
Pi is an irrational number, a decimal that won't stop. It has been calculated to ten trillion digits, which is kind of silly because just 39 digits are enough to calculate the circumference of a circle the size of the observable universe with an error no larger than the radius of a hydrogen atom.To five places, it's 3.14159

Assuming that the last two digits are indicators of precision, there are 5 significant digits.
The number of digits in a number is known as precision of a number. Depending on the precision required, the number is quantized to give the final number.
Start by measuring accurately, then just remove digits until you have the precision you want.
