Step-by-step explanation:
<h3>Definition(s):</h3>
1. <em>Circumference</em>
The outer boundary, especially of a circular area; <em>perimeter</em>.
2. <em>Radius</em>
A straight line extending from the center of a circle or sphere to the <em>circumference</em> or <em>surface</em>.

<h2>solution</h2>
The circumference of a circle can be obtained by using the equation below:

where the mathematical constant,
, has a value of approximately 3.14 and
represents the radius of the circle.
All we have to do is multiply the given radius by two and multiply that value by
to determine C:



First you find the slope using y2-y1/x2-x1
which would be -6 and then to find the y-intercept plug in either (-3,-1) or (-4,-7) in x and y and plug in the slope -6
-1=-6(-3)+b
-1=18+b
-18. -18
-19=b
y=-6x -9

The answer is 20%
If 50 is your 100%, take 100 and 90 for example it would be obvious that is it 10% off, so with 50 since it is half of 100 you double the 10% which will be 20%. :)
