Asked: If the lines shown in the picture touch the circle only at points A and B, what is the circumference of the circle?

(1) The distance between C and A is 8
The radius of the circle is unknown
NOT SUFFICIENT

(2) The distance between A and the center of the circle is 6 units.
Radius of the circle = 6 units
Circumference of the circle = \(36 \pi\) units
SUFFICIENT

IMO B
