An equilateral triangle of side 6 cm is inscribed in a circle. Then radius of the circle is

Solution

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 = $$\frac{side}{\surd{3}}$$

=> $$ r= \frac{6}{\surd{3}}$$

=> $$r = 2\surd{3} $$
