Let the Radius of First and Second Circle be r and R.
A/Q,
r:R = 2:3
RARIO OF CIRCUMFERENCE= 2πr:2πR = 2:3
A/Q,
r:R = 2:3
RARIO OF CIRCUMFERENCE= 2πr:2πR = 2:3

Circumference of the circle =2 pie r
Therefore...let Radius be 2x and 3x respectively of two circles.
Then, Circumference of 1st circle = 2*22/7*2x.
Circumference of 2nd circle =2*22/7*3x.
Now, as they are in ratio.. So, we can write them in fraction form also.
So, write them in fraction form and solve further...
You'll get answer as 2:3.
Hope it helps you. ✌️.
