The 6-pointed star can be viewed as 12 equilateral triangles.

The radius of the circle circumscribing the 6-pointed star is twice the altitude of one of those triangles.

The side of each triangle is 25.
The altitude of each triangle is 25*(sqrt(3)/2).
The radius of the circumscribed circle is 25*sqrt(3).
