In circle o, ab = 12 centimeters and maob = 60°. since 60° is of 360° then the length of is the circumference of the circle. use this fact to find the exact length of

In Circle O, length of minor arc AB = 12 centimeters

<AOB = 60°.

Since 60° is one sixth of 360°

So the length of the arc must be one sixth of the circumference or length of the circle.

Arc AB= 12

So Arc AB = of circumference

Cross multiplying we get

Circumference C = 12 ×6 = 72 cm

Hence the circumference of the circle whose arc measures 12 cm making 60° as the central angle is 72 cm.
