Answer 2

Answer:

The Final answer is $=\sqrt{3}$

Solution:  

According to the question,

Given Data:

The side of a equilateral triangle is 3cm.

To Find:

Circum Radius

Step-by-step explanation:

Step 1:  

For any triangle,

Circumference $=\frac{a b c}{4 A}$

a,b,c = length of sides

Step 2:

abc$= 3 \times 3 \times 3 =27$

$=\frac{\sqrt{3}}{4} \mathrm{a}^{2}$

$=\frac{\sqrt{3}}{4} (3 \times 3)$

$=\frac{9 \sqrt{3}}{4}$

Step 3:

4A $=\frac{9 \sqrt{3}}{4} \times 4$

$=9 \sqrt{3}$

Step 4:

Circum Radius $=\frac{a b c}{4 A}$

$=\frac{27}{9 \sqrt{3}}$

Step 5:

Result:

$=\sqrt{3}$
