Answer:

GIVEN :-

The ratio of the radii of the circles = 3:5

Radius of first circle = 3x

Radius of second circle = 5x

TO FIND :-Find the ratio of their circumferece.

SOLUTION :-Circumference = 2πr

= 2π×3x=6πx

circumference of second circle = 2πr

= 2π×5x=10πx

Ratio between their circumference

= 6πx:10πx

= 16:10

= 3:5

- I Hope it's Helpful.
