Step-by-step explanation:

Given:-

The radii of two circles are in the ratio 2:3

To find:-

What is the ratio of their circumference?

Solution:-

The radii of two circle = 2:3

Let they be r1 = 2 x

r2 = 3 x

we know that

Circumference of a circle = 2πr units

Ratio of their Circumference

=>2π(2x):2π(3x)

=>4πx:6πx

=>4:6

=>2:3

Answer:-

The rati of their circumference = 2:3

Conclusion :-

The ratio of circumference of the two circles is equal to the ratio of radii of the two circles.

Used formula:-

  • Circumference of a circle = 2πr units

Where, π= 22/7

and r=radius of the circle
