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
Answer:
It would<u> reduce the dependence on traditional ways of living.</u>
Explanation:
- Living in a place were water and space are heated directly by sunlight or sun influence would be quiet interesting and challenging as the sun is the nearest star to planet earth and this star will continue to grow in size, and also the resources on surface of earth are finite and thus any overuse of these resources can lead to their depletion.
- Use of this solar light or heat is essential as its an inexhaustible resource that can be stored at specific temperatures and used in terms of lightning, billing waters from heat generated by sun photovoltaic cells.
- The same energy that is needed r warm the surface of the earth falling on rooftops of the house can recharge the energy bill of the entire country for which sun harvesting has to be implemented.
- Like solar terracing and many farmers and people have done gardening on their roofs and many innovative techniques are being developed for a sustainable future.
Solar is inconsistent due to time of day and/or weather.
Nuclear creates long lasting radioactive waste.
Hydroelectric construction of this resource destroys river ecosystems.
Coal creates pollution when burned.
Wind is inconsistent due to only to weather.
The solutions to environmental problems are “coordination of environmental efforts between sectors”, “enforcement of environmental regulations”, “sustainable land management practices”.
<u>Explanation:
</u>
The environmental problems in any region can be a threat to that region since it may affect their health to a greater extent. In order to eradicate any environmental problem in a region there must be a good coordination existing between sectors which will result in solving an environmental problem easily and quickly.
Strict enforcement of environmental regulation acts and policies also plays a major role in solving the environmental problems. Land management practices are those that combine the land management, water bio diversity and other resources in environment for meeting the needs of human beings.
Answer:
Ice wedges are a big cause of potholes in roads and streets. As ice forms in the cracks of a street, the water expands and pushes against the surrounding rock, making the cracks wider, eventually breaking apart the rock.
