Answer 1

The circumference of the green circle is about 138.23 meters.

The circumference of the blue circle is about 69.115 meters.

Explanation:

Considering 22 m as the green circle radius and 11 m as the blue circle radius:

The circumference of the green circle is about:

`C=2\pi r`

`C=2\pi 22\\C=44\pi \\C=138.23 m`

The circumference of the blue circle is about:

`C=2\pi r`

`C=2\pi 11\\C=22\pi \\C=69.115 m`
