Seismometers are tools which measure motion in the ground including seismic waves generated by earthquakes, volcanoes, and other activities which might create seismic waves. Seismometers measure any movement of seismic activity in the earth and today this is done by electronic means whereby the machine measures any changes in seismic activity in the surrounding areas of the seismometer. The first seismometer is believed to have been invented by Zhang Heng of China's Han Dynasty in 132 AD.
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
