1. Given two triangles and a circle with radius 1 arranged as follows: a) What is the length of the inner triangle's perimeter to four decimal places? b) What about the outer triangle's perimeter? c) Now answer the same question for two squares, similarly arranged.d) What about for pentagons? e) Or an "n-sided" shape (you're probably going to have to use a trig function in here - which is sort of cheating, but not really)
