Answer:
Step-by-step explanation:
If ABC is a triangle with sides a, b and c then
The relation between the Area A side lengths a, b, c; circumradius R and inradius r is
A = rs ..where s is semi-perimeter of the triangle
Given the length of the side of the equilateral traingle =
Area A of the traingle
Radius of circumcircle
[√(3)×√(3)×√(3] ÷ 4A
R= 1unit
