Question

The radii of two circles are in the ratio 2: 3. What is the ratio of their circumfere
​

Answer 1

Answer:

2:3

Step-by-step explanation:

Let the radius of 1st circle (r1) be 2x

and the radius of 2nd circle (r2) be 3x

Now,

Circumference of 1st circle/Circumference of 2nd circle = 2π r1/ 2π r2

= r1 / r2

= 2x/ 3x

=2/3

= 2:3 Ans.
