Question

What is the approximate sum of the radius of the circumcircle and the inner circle?

Answer 1

Answer:

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

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

Radius of circumcircle

[√(3)×√(3)×√(3] ÷ 4A

R= 1unit

$r + r = \frac{3}{2} = 1.5units$
