Answer 1

Answer:

circumference of A circle is 2πr

let the radii ratio be x then 2x and 3x

now solve

2×22×2x÷7=2×22×3÷7

Answer 2

Answer:

The answer is 2:3

Step-by-step explanation:

Let r is equal to radius of first circle and let R is equal to radius of second circle.

∴ r/R = 2/3 ........... 1

Then, the ratio of circumference of circle is

2πr/2πR = r/R

i.e, 2/3.

Hope this helps.

Thank you.
