Acircle has a diameter
with endpoints at (10, 8)
and (5, 4). what is the
circumference of this
circle?

The circumference of circle is 20.096 units

Solution:

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

The distance between two points is given by formula;

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

Substituting the values we get,

Thus the diameter is 6.4 units

The  circumference of the circle is given by formula:

Where "d" is the diameter of circle

Thus circumference of circle is 20.096 units
