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
D A A C A C A B A D A C B B 1/1/3 B 43/1/5 A A
The answer is D 16a: 1,2,3,4,8,16 and 18ab:1,2,3,46,9,18 a,b
