Answer:

D

Step-by-step explanation:

Circumference = 2 * pi * r

Circle A / Circle B = 2 * pi * 8 / 2 * pi * 2

You need to take note of the right side. The 2s cancel and so does pi

Circle A/ Circle B = 8/2

Circle A / Circle B = 4/1 = 4

Which is D

Answer:

1/4

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 1/4 since 3.14 x 2 = 6.28

Also since the radius is 2 times longer
