Answer:
The Correct answer is:
A. You aren’t telling me anything I don’t already know.
Step-by-step explanation:
For circumference it’s 12x3.14= 37.68
If I understand your question well, I suppose you mean

Answer:
227 sides
Step-by-step explanation:
The sum of the interior angles of a convex polygon is S=180(n-2) where n is the number of sides. If S=40500, then we have our equation 40500=180(n-2) and we can solve for n:
40500 = 180(n-2)
225 = n-2
227 = n
Therefore, the number of sides in the regular polygon is 227.
