CORRECT ANSWER IS 12√3 and that is EXACTLY TWICE the result he got of 6√3 which is
not correct, only half of the correct answer
Each side of a circumscribed equilateral triangle is 16 meters.
Find the radius of the circle.
The radii of the circle are perpendicular bisectors to the 16 meter triangle sides.
The radii, an 8 meter segment form the legs of a 30 60 90 triangle and while segments
from the vertices of the triangles to the center of the circle form hypotenuses.
The lengths of the radii are therefore 8/√3 = 8√3/3 meters
That is approximately 4.61 meters if you need a numerical approximation
The other answerer made a slight scale error in the other direction, his result is EXACTLY TWICE
the correct answer thus the correct answer of
8√3
▬▬ meters is exactly half of the result that he got.
