find the exact area of a regular dodecagon inscribed in circle with the radius R
This question is from textbook dicovering geometry

A regular dodecagon has 12 equal sides.
The radius of the dodecagon is equal to the radius of the circumscribed circle.
Using the formula for the area of a regular polygon of n sides and having a radius R:
Substitute n = 12 and simplify.



...and since the value of R is not provided, this is as far as we can go!
