Six bangles of different colors having radius 4 cm each are placed inside a circle. The bangles are just touching each other. The circle touches them outside. Find the radius of the circle.

• let, one bangle is placed in the center, and the rest 5 bangles are surrounding it.
  radius of the center bangle+ diameter of the outside bangle= 4+8= 12 cm
  therefore, Ans= 12 cm

• For bangles placed in such a way that their centers form a hexagon,
  Distance of each vertex of hexagon from the center of hexagon/bigger circle = length of hexagon side/2 sin(180/6) = 8
  Thus, radius of bigger circle = 8+4 = 12 cm
