Hello good morning
Here u can find ur answer....
Circumference of a circle = 2 [ pi] r
The ratio of radii if a circle =3:5
Circumference would be 2* pi* 3x/2*pi*5x
When everything cancels, the ratio remain 3:5
Hope it helps

circumferences = perimeter of the circle = 2 x (22/7) x radius
the radius be 3x and 5x
22/7=pie
2 x22/7 x 3x / 2 x 22/7 x5x
=3:5
