Pi is about 3.14159265. You can round that to as many or as few significant digits are are appropriate for a particular application.
Pi is not a rational number, that is, it can not exactly be expressed as the ratio of two integers. Of course you can approximate it through rational numbers, like 3.14, or 22/7.
It is an approximate value for pi
First of all it is spelled as 'Cosine' , and shortened to 'Cos'. pi and has the approximate value . 3.141592..... Hence Cos(pi) = Cos( 3.141592.... ) = 1.0 ( On calculators it may shown 0.998.... , this is because the value of 'pi' is only approximate.
Because 22/7 is the approximate value of pi as a fraction but the exact value of pi has never been determined.
No because the value of pi as regards to a circle is an irrational number

The approximate value of pi is 3.14159265.
The approximate value of pi up to the fifth decimal place is 3.14159
3.14
I Think the value of pi is 3.1416 ...
3.14 or 3.142
It is an approximate value for pi
22/7 is only an approximate value of pi
Because 22/7 is the approximate value of pi as a fraction but the exact value of pi has never been determined.
No because the value of pi as regards to a circle is an irrational number
3.142
3.14 is the approximate value of pi.
