Question

An equilateral triangle has side 2 root 3 cm. The radius of its circumcircle will be

Answer 1

divide a with root 3

2root3 divide by root 3

answer is 2 cm

Answer 2

Answer: The radius of the given equilateral triangle is 2 cm

Step-by-step explanation:

Side of triangle; a = 2√3 cm

Let R be the radius of circumcircle then the radius of circumcircle of an equilateral traingle is given by

$R= \dfrac{a}{\sqrt{3} } \\\\\Rightarrow R = \dfrac{2\sqrt{3} }{\sqrt{3} } =2 cm$

Hence, the radius of the given equilateral triangle is 2 cm
