Answer:
let the radius of the circle be = x
the radius of the first circle = 4x
the radius of the second circle = 5x
circumference of the circle = 2πr
circumference of the first circle = 2. 22/7 . 4x
circumference of the second circle= 2 .22/7. 5 x
the ratio of the circumference = circumference of first circle / circumference of second circle
= 2.22/7.4 x / 2.22/7.5x
=4x/ 5x
= 4/5
=4:5
