If an equilateral triangle inscribed in a circle formaula for side s = sqroot(3)*radius

If a circle is inscribed in an equilateral triangle formula is radius= sqroot(3)*side /6

Do you mean the length of one side of the tringle will be suare root x 3 (by the way, where did the 3 come from) x the radius?

and for the circle inscribed in a triangl, do you mean square root of radius x 3 x the length of one side / 6 (by the way where did you get the 6 from) ?
