Question

An equilateral triangle has side $2\sqrt{3}cm$. The radius of its circumcircle will be

• A. 2 cm
• B. $\sqrt{3}cm$
• C. 3 cm
• D. 4 cm

Answer 1

Answer: (A)

2 cm

Given,

The side of the equilateral triangle $=2\sqrt{3}cm$

We know that the radius of its circumcircle will be

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

$=\frac{2\sqrt{3}}{\sqrt{3}}$

$=2cm$

Hence, this is the answer.
