Answer:
539 cm²
Explanation:
Height of the cylinder, h = 14 cm
Base diameter = 7 cm
Base radius, r = 7/2 = 3.5 cm
Volume of the cylinder = πr²h = 22(7) × (3.5)² × 14 = 539 cm²
Answer:
Volume = 539cm³
Explanation:
Height = 14
Radius =
[tex] \frac{7}{2}[/tex]
Volume =
[tex]\pi {r}^{2}h[/tex]
[tex] \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} + 14 \\ = 11 \times 1 \times 7 \times 7 \\ = 539 \: {cm}^{ 3} [/tex]

The type of radiation Earth receives from the sun is solar radiation.
What is Earth?Earth is a planet present in the solar system having the existence of life. This is the only planet on which life is possible due to living conditions that ensure the availability of water which is important for survival.
The main form of energy that the sun sends to Earth is solar radiation. It consists of a variety of electromagnetic radiation, such as infrared (IR), ultraviolet (UV), and visible light (light).
The rapid movement of charged particles as they pass through the magnetic field of the sun results in the production of X-rays and gamma rays.
The nuclear events that take place in the core of the sun produce particles. These are high-energy forms of electromagnetic radiation that are produced by the sun.

Moon is the bodies in the solar system do we have data about the subsurface layers. Hence, option B is correct.
What is meant by subsurface layers?The technique used to define subsurface layers, which also includes soil and rock layers, is intended to characterize the shallow material layers that lie directly below the ground's surface.
In essence, you model the layer's base surface or underbelly before specifying the layer's classification material type. Bsurface dirt is soil that is more than 2 feet below the surface of the land.
Iron oxides are principally responsible for this layer's hue because it typically includes less organic material than the A horizon. Clay minerals and iron oxides gather due to weathering. Materials that fall from the topsoil collect in this layer of soil.

Why is military interventions such a risky proposition for other countries watching this Ukraine and Russia conflict unfold? Use a specific example.
Answer:
M.A.D.
Explanation:
M.A.D., which means Mutually Assured Destruction, is the main reason why European powers are hesitant to intervene in the war. Russia, if feeling as though they were going to lose or be attacked, would most likely launch their nuclear arsenal as a last ditch effort to win or assure that if Russia falls, so does everyone else. This would be devastating because the United States and Russia have so many nuclear bombs that they could destroy the world many times over. There would be no survivors in a nuclear war.

Studying Geography will help me better understand what is going on in other places as it relates to where I live. This is helpful when I am watching the news or reading a newspaper.
As it will take every person in the world working together to fight the battle we face, studying geography can help everyone fight climate change.
Being knowledgeable in geography also helps in understanding cultures. Every place around the world is different. Even here in America, things are done differently from place to place. Having a better understanding of each other's culture can lead to a more peaceful existence.
History is important to understand. "Those who do not learn history are doomed to repeat it". A quote by writer and philosopher George Santayana. It is impossible to study geography without knowing the history and it is imperative we know what went wrong in the past so as not to let it become our future.
Last but not least, the global community is a reward for studying geography. With the vastness of our virtual capabilities we, as a whole, have built a global community. While studying geography my curiosity has led me to social media. I have sought out people from other countries to ask questions about where they live. There is so much that is not written in the books. Now I have friends all over the world.

Most earthquakes are a result of a. Erosion of bedrock. B. Mantle upwelling. C. Movement of rocks along faults. D. A sudden change in atmospheric pressure
Answer:
is the C
Explanation:
Although the interaction between tectonic plates is the main cause of earthquakes, it is not the only one. Any process that can achieve large concentrations of energy in rocks can generate an earthquake whose size arose, among other factors, from how large the stress concentration zone is.
i hope these help's you, if you give me the crown i will appreciate it
Most earthquakes are a result of the movement of rocks along faults. Thus, option C is correct.
A fault slips suddenly, resulting in an earthquake. Although the tectonic plates are always moving slowly, friction causes them to become impermeable at their borders. An earthquake occurs when the stress on the edge exceeds the friction, releasing energy in waves that flow through the earth's crust and produce the shaking we experience.
The Pacific Plate and the North American Plate are the two plates that makeup California. The majority of the Pacific Ocean's floor and the California Coastline are both part of the Pacific Plate. Most of the North American Continent and portions of the Atlantic Ocean's floor are made up of the North American Plate. The San Andreas Fault serves as the main dividing line between these two plates.

Why do coastal regions, near

rainfall?
A. The mountains trap the weather coming from the
sea.
B. The mountains attract humidity.
C. The mountains serve as a catalyst to form clouds.
Answer:
I think it would be B. The mountains attract humidity.
Explanation:
When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop. When the air descends the leeward side, it warms and is drier because the moisture in the air was wrung out during the ascent. This area with a lack of moisture is known as a rain shadow.
Answer:

A. The mountains trap the weather coming form the sea

What is happening to european and african populations as a result of high dependency ratios? european and african populations are growing younger. european and african populations are growing older. european populations are growing younger, and african populations are growing older. european populations are growing older, and african populations are growing younger.
Answer:
European populations are growing older, and African populations are growing younger.!!!
Explanation:
European populations are growing older, and African populations are growing younger. This is what is happening to European and African populations as a result of high dependency ratios. The correct option is D.
What are dependency ratios?The dependency ratio is the number of people who are too young or too old to work and therefore have to be supported by the working population in a given society. People who are too young to work include children under the age of 15, while those who are too old include those over the age of 65 years.
High dependency ratios can have a significant impact on the demographic characteristics of a population. When a population has a high dependency ratio, it implies that there are fewer working-age people in the population, and more people who are either too young or too old to work.
In Europe, there is a high percentage of older people, which means that the population is aging. In Africa, the population is younger because there are more working-age people who support the older and younger population. Consequently, the high dependency ratios lead to the growth of older populations in Europe and younger populations in Africa.
Therefore, the correct option is D.
