OA is D ???
Circumference of the circle is 2*pi*r
so the radius of each circle is 1
so if see closely .... each side of the triangle is a radius by itself.....
whuch in turn inference for all 1 on each side of the triangle
so using the formula for equilateral triangle area =(root3/4 )*r^2
r=side=radius
root3/4 is the answer

D
triangle is an equilateral triangle.
formula for the area of an equilateral triangle = ( (Base)^2 * sqrt (3) ) / 4
AB = base = radius
circumference = 2PiR
so 2PiR = 2Pi
so R = 1
then just plug 1 into the area formula above. done.

by construction its an equilateral triangle....of length radius of the circle...circ,ference is 2PIr = 2PI so r =1.
If u know the formula of equilateral triangle: (3^1/2)/4*s^2 so result will be (3^1/2)/4
