I hope it will help you thanks

Answer 2

Answer:

5:3

Step-by-step explanation:

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

C 1and C 2 respectively.

Circumference of a circle =2πr

Then, C 1

=2×π×5x=10πx and C 2

=2×π×3x=6πx

∴

C 1/C 2= 6πx/10πx

C 1/C 2= 5/3

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