Explanation:
Given:
Radius (r) = 2 units
Height (h) = 9 units
π = 3.14
Required:
Volume of the cylinder
Solution:
Volume = πr²h
Plug in the values
Volume = 3.14*2²*9
Volume = 3.14*4*9
Volume = 113.04 cubic units
Answer:
animal wastes and fertilizers
Explanation:
The majority of the nitrates that are polluting the rivers come from the animal wastes and from the fertilizers used in the agriculture. The increased amounts of nitrates in the rivers causes eutrophication. This basically means that the water is becoming over-saturated with nutrients. This leads to the spreading out of the algae. As the algae spread out more and more, they cover the surface part of the water, so large portions of the rivers do not receive sunlight, which kills of the organisms that use photosynthesis. Further, the algae reduce the amount of oxygen in the water, often resulting in dying out of the fishes. It is a chain reaction that leads from one thing to another and the end result is devastating.
