Answer 2

Answer:

The radius of its circumcircle is 3 cm.

Step-by-step explanation:

Given : An equilateral triangle has its side of 3√3 cm.

To find : Radius of its circumcircle ?

Solution :

The formula is given by when an equilateral triangle is in circumcircle is

$r=\frac{s}{\sqrt3}$

Where, r is the radius of the circumcircle.

s is the side length of the equilateral triangle.

We have given,

$s=3\sqrt3$

Substitute in the formula,

$r=\frac{s}{\sqrt3}$

$r=\frac{3\sqrt 3}{\sqrt3}$

$r=3$

Therefore, The radius of its circumcircle is 3 cm.
