    Finding the perimeter and area of polygons

    I need to find the perimeter and area of polygons. I do this by inscribing them in a circle. I need to do this for 3, 6, 9, 12, and 15 sided.
    Is there some kind of pattern or relation?

    Have you tried doing the first few to see if you can see a pattern?

    What values did you get for area & perimeter for the first few?

    3-gon-
    perimeter= 3sqrt(3)r
    Area = (3sqrt(3)r^2)/4

    6-gon-
    Perimeter = 6r
    Area = (3sqrt(3)r^2)/2
