Question

The ratio of radii of two circles is 3:4 then the ratio of their circumferences?

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Let the radii of the given circle be 3x and 4x, respectively and let their circumference be C1 and C2., respectively.

$then \\ \\ \frac{c1}{c2} = \frac{2\pi(3x)}{2\pi(4x)} = \frac{3}{4}$

✅ hence the ratio of the circumference of the given circles is 3:4.
