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

Answers

Answer 1
Answer:

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!
Answer 2
Answer:

Final answer:

The ratio of the circumferences of two circles is the same as the ratio of their radii. In this case, where the ratio of the radii is 3:7, the ratio of their circumferences will also be 3:7.

Explanation:

The ratio of the circumferences of two circles is equal to the ratio of their radii assuming all measurements are in the same units. This relationship is due to the formula for the circumference of a circle, C=2πr, where C is the circumference and r is the radius. Seeing this formula, we can ascertain that if we increase the radius, we increase the circumference by the same factor. Therefore, if the ratio of the radii of two circles is 3:7, the ratio of their circumferences will thereon also be 3:7.
