Question

In Circle O, AB = 12 centimeters and mAOB = 60°. Sin 60° is of 360° then the length of is the circumference of the circle. Use this fact to find the exact length of . 4(pi) cm 24(pi) cm 4 cm 8(pi) cm

Answer 1

Do you know the circumference formula?

Answer 2

We know the circle is 360 deg.
We have an arc AB of 60 deg which is 12 cm.
Circumference is:
\[C = 2\pi*r\]

Answer 3

And we have:
\[AB = (2\pi*r)*60/360 = 12 cm\]

Answer 4

And what is the exact question and your plan?
