Answer:

Step-by-step explanation:
<u>Formula for circumference of a circle is</u>:
Circumference = 
<em>Given circumference of the ring is
</em>
<em>Now solving for the radius gives us:</em>

We know that area of a circle is
, substituting the value of r we found, we get the area as:
area (A) = 
Hence the Area (A), in terms of
is
I found this --The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.
M 1: 64
M 2: 49
M 3: 87
M 4: 44
