The sequence is pretty easy to explain and suffices to disprove it...I don't think it's sufficient, you can't assume from the start what the perimeter is, because it's what you're trying to solve. If pi = 4, then the perimeter of the circle is 2*pi*r = 4.
This assumption is IMO also a problem for the limits of sin/cos, they're defined based on a value of pi, so of course they'll spit out pi if you take sin^-1(1) in a program that knows sin(pi)=1.
