The ratio of the radii of two circles is 3: 7. what is the ratio of their circumferences? a. 1: 1 b. 3: 7 c. 3: 14π d. 6π: 7 e. 9: 49

Hey there!!

The ratio radius is given as 3:7

... Let's take the first circle's radius as 3 and the radius of the second's circle as 7.

The formula for the circumference as 2π(radius)

The circumference of the first circle as 2π(3)

... 6π

The circumference of the second circle as 2π(7)

... 14π

Ratio = 6π:14π

... 3:7

Hence, the answer would be option (B)

Hope my answer helps!

the best estimate is 3 because   8 can only go into 24 3 times
