Answer:

Step-by-step explanation:
<u>Formula for circumference of a circle is</u>:
Circumference = 
<em>Given circumference of the ring is  </em>
</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:
, substituting the value of r we found, we get the area as:
area (A) = 
Hence the Area (A), in terms of  is
 is  
 
 
        
                    
             
        
        
        
2s + s = 36
3s = 36
s = 36/3
s = 12
