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>
![d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5Cleft%28x_%7B2%7D-x_%7B1%7D%5Cright%29%5E%7B2%7D%2B%5Cleft%28y_%7B2%7D-y_%7B1%7D%5Cright%29%5E%7B2%7D%7D)
Here the points are (10, 8) and (5, 4)
![(x_1, y_1) = (10, 8)\\\\(x_2, y_2) = (5, 4)](https://tex.z-dn.net/?f=%28x_1%2C%20y_1%29%20%3D%20%2810%2C%208%29%5C%5C%5C%5C%28x_2%2C%20y_2%29%20%3D%20%285%2C%204%29)
Substituting the values we get,
![\begin{aligned}&d=\sqrt{(5-10)^{2}+(4-8)^{2}}\\\\&d=\sqrt{(-5)^{2}+(-4)^{2}}=\sqrt{25+16}=\sqrt{41}\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%26d%3D%5Csqrt%7B%285-10%29%5E%7B2%7D%2B%284-8%29%5E%7B2%7D%7D%5C%5C%5C%5C%26d%3D%5Csqrt%7B%28-5%29%5E%7B2%7D%2B%28-4%29%5E%7B2%7D%7D%3D%5Csqrt%7B25%2B16%7D%3D%5Csqrt%7B41%7D%5Cend%7Baligned%7D)
![d = \sqrt{41} = 6.4](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B41%7D%20%3D%206.4)
Thus the diameter is 6.4 units
<em><u>The circumference of the circle is given by formula:</u></em>
![c = \pi d](https://tex.z-dn.net/?f=c%20%3D%20%5Cpi%20d)
Where "d" is the diameter of circle
![c = 3.14 \times 6.4 = 20.096](https://tex.z-dn.net/?f=c%20%3D%203.14%20%5Ctimes%206.4%20%3D%2020.096)
Thus circumference of circle is 20.096 units
Explanation:
In the planet Earth , there are movement like the plate tectonics , which makes the surface of earth crust to move continuously , which is capable to generate lines of individual islands and volcanoes .
But these type of tectonic movements are not possible in Venus or Mars .
Thereby making the surface of earth different from that of planet Mars and Venus .
After looking at the photograph given above, one sedimentary rock that probably metamorphosed to form rock on unit 6 is called limestone. You can also use the sedimentary rock called dolostone. Both will be acceptable answers to this question.
