The two circles shown above have radii of 2 in. and 6 in.
What is a circum A over b?

Answer:
1/3
Step-by-step explanation:
For the first circle 2 x 2in = 4 to find diameter
4 x 3.14 = 12.56
6in x 2 = 12
12 x 3.14 = 37.68
simplify
12.56/37.68
6.28/18.84
3.14/9.42
So the answer is 1/3 since 3.14 x 3 = 9.42
Also since the radius is 3 times longer
