Answer:
Circumference of Green Circle = 138.16 m
Circumference of Blue Circle = 69.08 m
Explanation:
The radius of the green circle = 22 m
Radius of the blue circle = ½ the radius of the green circle = ½*22 = 11 m
Circumference is given as C = 2πr
Circumference of the Green circle = 2*3.14*22 = 138.16 m
Circumference of the Blue Circle = 2*3.14*11 = 69.08 m
