Area of a nonagon with a circumradius of 2 units is 11.57 square units.
The area is indeterminate, since the shape can be a long thin nonagon with minimum area or a regular one with maximum area.
It is 72.3 square units, approx.
For any nonagon in general:Perimeter = (side-1 + side-2 + side-3 + . . . . . + side-8 + side-9)For a regular nonagon:Perimeter = 9 x (length of one side)
For a 9 sided polygon it is: 0.5*(92-(3*9)) = 27 diagonals
