Due to its energy consumption, desalinating sea water is generally more costly than fresh water from surface water or groundwater, water recycling and water conservation. However, these alternatives are not always available and depletion of reserves is a critical problem worldwide.[5][6] Desalination processes are usually driven by either thermal (in the case of distillation) or electrical (in the case of reverse osmosis) as the primary energy types.
Explanation:

The formula is above, so if you plug it in it should be 34 squared times 27.
24 squared is 1156. Multiply 1156 by 27 and you have 31212. If you have to solve it with 3.14, just multiply that by 3.14 (Would take too long for me).
The economic needs that drove international trade from 1300-1750 were the discovery of spices and silks by the Europeans.
- International trade is a form of trade which involves the exchange of goods and services among several countries.
- It should be noted that there was a commercial revolution which was based on trade. Europeans discovered silk, spices and other essential commodities. This brought about international trade.
- The goods discovered were sold to other parts of the world. Mercantilism and new sources of wealth were also practiced by several countries in order to boost their development.
In conclusion, the international trade led to the development of commerce and increase in the gross domestic product of the countries involved.
