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
