The circumference of circle is 20.096 units
<em><u>Solution:</u></em>
Given that circle has a diameter with endpoints at (10, 8) and (5, 4)
To get the diameter, find the distance between the end points
<em><u>The distance between two points is given by formula;</u></em>

Here the points are (10, 8) and (5, 4)

Substituting the values we get,


Thus the diameter is 6.4 units
<em><u>The circumference of the circle is given by formula:</u></em>

Where "d" is the diameter of circle

Thus circumference of circle is 20.096 units
The answer would be y axis, x axis, another y axis and x axis. One then can reflect y axis (5,1) and would reflect to x axis (5,-1) And then across y axis (-5,1) and would back to (-5,1). Hope this is the answer and would help.
