The ratio of the radius of the circles are 2:3
According to question , the radius is 2x and 3x
We know the circumference of circle is 2πr
1️⃣ therefore the Circumference of the first circle is
2πr
= 2× (22/7)× 2x
2️⃣ The Circumference of the second circle is
2 × (22/7) × 3x
The ratio of the Circumference is
[ 2× (22/7)× 2x] / [ 2×( 22/7)× 3x ] = 2/3 = 2:3
