How would I calculate the perimeter of a hexagon (which can be divided into 6 congruent equilateral triangles) which is inside a circle with an area of 314^2 cm?

Many thanks

  1. Figure the radius of the circle from the area.

    Then, that radius is a side to each triangle.

    Since the triangles are equalaterial, you know all sides, including the outside segment. But six outside segments make up the perimeter of the hexagon, right?
