22/7 is a rational number, and thus has a repeating or terminating decimal expansion. 22/7 is not pi. 22/7 is just a crude approximation sometimes used in place of pi. - Warren. Originally posted by luther_paul. the value itself is not infinite because it has an exact value (22/7).

Best Answer: No. Pi is a finite number. In Mathematics, infinite is defined as Existing beyond or being greater than any arbitrarily large value. Pi is approximately 3.14159. 3 is a finite number and 4 is a finite number. There may be an infinite number of numbers between 3 and 4, but each number is finite. The absolute value of Pi is a difficult number to come by. If we take the decimal number of 1.3, we get 0.3333333333....

I know pi can be calculated by the infinite sum of the series, where every other term's coefficient is negative (i forgot how to write this in sigma notation, forgive my bad math). So while pi itself may not be rational, it can still be written as a sum of rational numbers.

What do u mean pi is infinite? the value itself or the digit? if u are talking about the digits, its infinite because it is an irrational number, meaning unending digits. the value itself is not infinite because it has an exact value (22/7).

Also, even if it is infinite, how do we know it's non-repeating? Maybe the set of digits that is in fact repeating is bigger than calculable with all the matter and energy in the universe, again, but that doesn't mean that it isn't repeating, once that larger than universe number is reached.

Now, the numbers like pi which can't be written as a fraction are called irrational numbers. These numbers will be infinite and never repeat. The problem is that it's often very tricky to prove that a given number is irrational, so I'm going to leave off here.

The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter π, sometimes spelled out as pi. In English, π is pronounced as pie (/paɪ/ , paɪ).

So because we know that if a number repeats it must be rational and because pi is irrational it can not repeat. As someone else pointed out we know that any finite number can be written as the ratio of two integers easily so as a consequence we know that since Pi is not rational then it must be infinite.

Hence combining these facts, we are sure that the digits of pi are infinite and non-repeating. To conclude, I would like to point out that most of the interesting features of pi have nothing to do with its decimal expansion 3.141592...

Pi may have an infinite number of places to the right of the decimal point when looking for the most accurate value, but Pi times the diameter equals the circumference. The circumference and the diameter or both finite. Because Pi has boundaries between 3 and 4, it is not infinite.
