What is the ratio of the circumference of the orange circle to the circumference of the blue circle?

a. 4pi/9pi
b. 3/2

B) 3/2

The radius of a circle is half its diameter.

Thus, the radius of the orange circle is 6, and the blue circle is 4

Thus the ratio is 4/6, which can be simplified to 3/2

Hope it helps <3 (Also, just answered this question for someone else!!)
