n, number of degrees of central angle

%28n%2F360%29pi%2A5%5E2=32
n=32%2A360%2F%2825pi%29
n=460.8%2Fpi---------------angle of the sector, degrees

Length of just the curved part:
%28n%2F360%292%2Api%2A5
%28%28460.8%2Fpi%29%2F360%29%2A2%2Api%2A5
%28460.8%2F%28360pi%29%292%2A5%2Api
460.8%2F36---------------length of the curved part.

Perimeter: 2%2A5%2B460.8%2F36, and you can compute the value.
