The 2 lines are parallel, so the 2 sides(e.g. 1 and 2/ 3 and 49) add up = 180 and In this case the 2 sides are equal as u can see from the original diagram so the angle of 2 is 180-49=131.

<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
