r1,r2 be the radius ofcircle c1 andc2 respectively
ratio =r1/r2= 2/3
ratio of circumference
= 2πr1/2πr2
=r1/r2
=2/3
=2:3

NeelamG: Is ryt??
PranjaliGautam: yes this is right
NeelamG: can u add it in brainlist
PranjaliGautam: I didnt ask this que.
NeelamG: ok

Hello,
let the radii of two circles be r and R.

we have:
2πr/2πR=2/3;
r /R = 2 / 3;

now ratio of  circumference of two circle:
C=2πr:2πR
then
2πr:2πR=r/R=2/3=2:3

Hence the required ratio is 2:3
Bye :-)
