An equilateral triangle of side 6 cm is inscribed in a circle. Then radius of the circle is
If the triangle is inscribed in a circle, then the circle is called as circumcircle.
We know that radius of circumcircle for any equilateral triangle = $$\frac{side}{\surd{3}}$$
=> $$ r= \frac{6}{\surd{3}}$$
=> $$r = 2\surd{3} $$
