Solution: For an equilateral triangle with side $ s $, the circumradius $ R $ is given by:
R = rac{s}{\sqrt{3}}
Wait â correction: The correct formula for the circumradius of an equilateral triangle is:
Actually, in an equilateral triangle, the circumradius is:
R = rac{s}{\sqrt{3}} \cdot rac{2}{1} \quad ext{Incorrect.}
Correct derivation: The height $ h $ of an equilateral triangle is $ rac{\sqrt{3}}{2}s $. The centroid (which coincides with the circumcenter) is at $ rac{2}{3} $ of the height from a vertex, so:
