Question #N416

A regular hexagon is inscribed in a circle with a radius of 6. What is the perimeter of the hexagon?
A. 12
B. 18
C. 24
D. 36

Correct Answer is: D

A regular hexagon can be divided into 6 equilateral triangles. The side length of each equilateral triangle is equal to the radius of the circle, which is 6. The perimeter of the hexagon is 6 times the side length of one of the equilateral triangles, or 6(6) = 36.
