Question #N394

A regular hexagon is inscribed in a circle with radius 10. What is the perimeter of the hexagon?
A. 30
B. 60
C. 60\sqrt{3}
D. 120\sqrt{3}

Correct Answer is: B

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 10. Thus, the perimeter of the hexagon is 6 * 10 = 60.
