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
Slope formula : (y2 - y1) / (x2 - x1)
now pick 2 points on ur line...
(1,2)......x1 = 1 and y1 = 2
(3,0)......x2 = 3 and y2 = 0
now sub
slope = (0 - 2) / (3 - 1) = -2/2 = -1 <== ur slope is -1
