To simplify, we need to find a number that can divide both the numerator and denominator equally. Can you find a number that will do this? I can't. So it is already simplified.
Answer:
where
denote arc lengths of two circles
Step-by-step explanation:
Let
denote arc lengths of two circles,
denote corresponding radii and
denote the corresponding central angles.
So,
and 
This implies
and 
As each circle has an arc where the measures of the corresponding central angles are the same, 

As radius of one circle is twice the radius of the other circle,


43% of 166 is 71.38 so it would be 71 to the nearest whole number!
I believe the answer is x = 1
