so we can find the circumference of the red circle that is this circle right here. We can find the circumference of that by using two. That's the arc length to is equal to 30 over 360 times circumference and then solve that equation for circumference. The blue circle, which is the outer circle. We're told that the radius is too are So that means whatever this answer is, whatever C is equal to, we want to double it, and that becomes our new circumference for the blue circle.
