When do the intigers of pi (22/7) repeat?

Actually, there are more numbers that do not repeat than numbers that repeat. \n\nAnd pi is one of those numbers that does not repeat.

PI= π = 22/7 = 3.1428571428571428571428571428571\n\nIn Euclidean plane geometry, π may be defined either as the ratio of a circle's circumference to its diameter, or as the ratio of a circle's area to the area of a square whose side is the radius. Advanced textbooks define π analytically using trigonometric functions, for example as the smallest positive x for which sin(x) = 0, or as twice the smallest positive x for which cos(x) = 0.\n\nAll these definitions are equivalent, they amount to the following numerical value of π, truncated to 50 decimal places:\n\n3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510

3.14159265358979 is as far as I have it memorized.  Yes, I'm a geek.  So your answer is 3.141592653589.\n\nSee?  Easy as pi!

when you multiply 247474747474.5 with Pi, you will get 777777777777.... :)

pi = 3.1415926\n\npi = 3.1416 (fourth decimal place, rounding up)

I don't know why people use 22/7 as an approximation for pi when another, easily remembered, ratio gives a much better approximation:\n\nWrite each of the first three odd numbers twice:\n113355\nUse the first three digits as the denominator and the last three as the numerator:\n355/113\nThis gives an approximation of pi that is accurate to 6 digits. 22/7 is only accurate to 2 digits:\n\n3.14159265 = pi\n3.14159292 = 355/113\n3.14285714 = 22/7

pi*(r^2)\n\nIt doesn't matter which unit you use, just make sure you're consistent.

He's more or less right.\n\nPi equals 3.14159265358979323846264338327940288419716939937510\n\n22/7= 3.1428571428571428571428571428571

pi doesn't equal 22/7 or 3.14.  those are just approximates, but fairly close approximates.\n\npi is how many radians there are in a half a circle-approximately 22/7 or 3.1415 radians.  a radian is the degree where the radius of the circle equals the outside segment of the circle at that degree.  (about 59 or so degrees if i remember correctly)

Sin x is periodic with period 2pi.  It takes ever smaller changes in x to get 1/x to change by 2pi.  \n\nSketch y=1/x then mark off equal steps along y.  Note that the closer you get to x=0 the smaller the x steps are to yield the fixed y steps, so sin 1/x repeats at ever smaller steps in x as x goes to 0.

pi is infinite, calculated out to at least a billion digits right now, and it has no iterations (meaning repeated numbers)...so there would be no final digits....

I understand what you are saying when you mention the permutations for 10 digits, but I think you're missing what it really means.  First, this isn't right to think of it this way to think about this.  Non-repeating doesn't mean that I can't find a string in the decimal expansion that's the same as an earlier string (for example, finding a piece 14159 later in pi isn't impossible).  What it means is that there is no point where the digits in pi *completely* repeat (i.e. it becomes something like 141591415914159.... on and on forever).  So you're right, it can include some kind of partial repeat, but non-repeating means it can't have a total repeat.\n\nYour comment about the permutations (not combinations) on the numbers {0,...,9} is right but it's used incorrectly also.  It's wrong because of what I mentioned above.  Basically it's assuming that once you pick a number you can't repeat it again in a 10 digit sequence, but that's clearly wrong (again, 14159 appears in pi, where 1 occurs twice).  So you have several right ideas here but you're combining them seomwhat incorrectly.\n\nHope this clears things up!!
