The difference between the radii of the circumscribed and inscribed

The difference between the radii of the circumscribed and inscribed circles of a regular triangle is equal to m, express the side of this triangle through m

The radius of a circle inscribed in a regular triangle is expressed by the formula:

r = a / 2√3, where a is the side of the triangle.

The radius of a circle circumscribed about a regular triangle:

R = a / √3.

The difference between these radii m is equal to:

m = R – r = a / √3 – a / 2√3 = a / 2√3.

From here we express the side of this triangle in terms of m: a = 2m√3.
