Answer 2

Answer:

Green circle: 138.16

Blue circle: 69.08

Step-by-step explanation:

Formula for circumference: 2πR

π ≈ 3.14

Green circle:

Radius: 22

Apply formula:

2 * 3.14 * 22 = 138.16

Blue circle:

Radius: Half of the radius of the big one, 11

Apply the formula once more:

2 * 3.14 * 11 = 69.08
