3.142
It is pi*d where d is the diameter of the circle. Since pi is a transcendental number, it is not possible to express its value exactly and so any value used for pi (3.14, 3.14159 or pi to 10 trillion digits) will still lead to an approximate answer.
3.14 is the approximate value of pi. Multiply the diameter of a circle by pi to get its circumference; multiply the square of the radius of a circle by pi to get its area.
Because - no matter how big a circle is - if you divide the circumference by the diameter - you will ALWAYS get the value of Pi ! As an approximate fraction, the value is 22/7. As a decimal , it's an infinite number.
The exact answer is 2*30*pi = 60*pi Using 3.14 as an approx value for pi, the approx circumference would be 3.14*60 = 188.4 inches
The approximate value of pi is 3.14159265.
The approximate value of pi up to the fifth decimal place is 3.14159

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.
3.142
3.14 is the approximate value of pi.
3.14 or 22/7
Depends on how approximate is acceptable. The approximation of 22/7 is often quoted.
