WebNov 8, 2016 · Answer: No. One should not confuse irrational with inaccurate. π is an irrational and precise number. If r = 1, A = π (or using r = 7, A = 49 π from comments above) this calculation is precise. π is the symbolic representation of the entire chain of that infinite sequence of numbers. It is as accurate as the symbol ∞ is (add to the list i and e ). WebMar 22, 2024 · 1 Answer Sorted by: 2 An irrational number cannot be expressed as a ratio of integers A/B. Suppose there is an irrational number N that you can add to itself to get a rational number. If 2N can be expressed as a ratio of integers A/B, then N can be expressed as A/2B, where both A and 2B are integers.

Transcribed Image Text: Use the Pythagorean theorem to find the length of the third side of the right triangle. Webpi + 1 - pi addition is commutable, so you can move things around as long as you keep the sign, so pi - pi + 1 is the same, and anything minus itself (even irrational numbers) is always 0, so all that is left is 1 = 1 If pi is 3.14159..., so if you subtract 1, you would have 2.14159..., but as you expected it does not mean much.
