Answer:

Let the radii of the given circles be 5x and 3x respectively and let their circumferences be C

1

and C

2

respectively.

Circumference of a circle =2πr

Then, C

1

=2×π×5x=10πx and C2

=2×π×3x=6πx

∴

C2C1=6πx10πx

C2C 1 = 35

Hence, the ratio of the circumference of the given circles is 5:3
