Answer:

Step-by-step explanation:

Let the larger radii be R units

And the smaller radii be r units

So, r:R = 2:5 (given)

As circumference = 2π*radius

So, circumference of larger circle = 2πR

And circumference of smaller circle = 2πr

Ratio, 2πr:2πR = r:R = 2:5

That means, the ratio of circumference will be simply the ratio of their respective radii.
