If the side of the regular hexagon above is 2, what is the circumference of the inscribed circle?  Pick one
A) 2∏√3
B) 3∏
C) 4∏/√3
D) 2∏/√3
E) ∏√3
Now AC will be 1 because circle is touching the midpoints of the circle.   Then we get kite ACBO.   We have AC = 1 and CB = 1, now we need to find BO which is radius   from triplets we get 30:60:90 = 1:√3:2   Now CBO is right angled triangle, then we get BO as √3.   r = √3...circumference is 2∏r is 2∏√3.   2∏√3nswer :option 2∏√3.
