because it is a never ending number. usually rounded to 3.14 or 22 over 7.

Answer:

The need to be accurate (have more decimal places in the case of pi) does not add anything to the quality of the work. In "quick" answers (such as a carpenter cutting a board to fit a circular hole) the ratio of 22/7 (3.1428) is often used for pi. Any table of pi values would tell you that first few decimals of pi are "really" 3.141592 ...

The quick and dirty method value is about 3 parts in 10,000 off. For cutting a board 10 feet long, this would be an error of about 1/32 of an inch. This would be an adequate accuracy for most projects.

Similarly the additional decimal values of pi (now listed as several million) add very little in the real world. The extra numbers do add confusion to the answer.

C = 2 pi (r) (two times pi times the radius of the circle) OR C = pi (d) (pi times the diameter of the circle). Often, pi is rounded off to equal 3.14, so if your calculator does not have a pi button on it, then use 3.14.

With pi rounded to 8 digits, it is 24.000008.
