Which expression represents the volume, in cubic units, of

Geography
1 answer:
MrRa [10]3 years ago
5 0

Answer:

C. π(5²)13 + 1/3π(5²)12 cubic units

Explanation:

The composite figure is made up of a cylinder and a cone.

The volume of the composite figure = volume of the cylinder + volume of the cone

For the CYLINDER:

Volume = πr²h

h = height of the cylinder = 13units

r = radius of the cylinder = 5units

Volume = π(5²)13 cubic units

For the CONE:

Volume of a cone = 1/3πr²h

height of the cone = 25-13 = 12units

Radius of the cone = radius of the cylinder = 5units

Volume = 1/3π(5²)12 cubic units

Volume of the composite figure will give: π(5²)13 + 1/3π(5²)12 cubic units

What is one benefit, and what is one challenge of the physical geography of the Arabian Peninsula and Anatolian and Iranian plat
velikii [3]

A major benefit of the Arabian Peninsula, and the Anatolian and Iranian plateaus is that they have natural resources.

A major challenge however, is that their locations make transportation quite difficult.

<h3>What is a Benefit of the Arabian Peninsula, the Anatolian and Iranian plateaus?
</h3>

The Arabian Peninsula is blessed with a huge natural resource reserve of oil with it having the largest oil reserves in the world.

The Anatolia and Iranian Plateaus are blessed with good soil which allows for extensive farming in wheat and other crops.

<h3>What is a challenge of the Arabian Peninsula, the Anatolian and Iranian plateaus?</h3>

The Arabian Peninsula is mostly made up of desert which means that getting around is quite difficult as there are little settlements.

The Iranian and Anatolian plateaus are quite high with this elevation making it quite difficult to get around as well.

olga55 [171]

Cambrian period do the Appalachian mountains first start to appear. The Paleozoic Era and the Phanerozoic Eon were both preceded by the Cambrian Period.

An crucial turning point in the evolution of life on Earth occurred during the Cambrian Period, when numerous invertebrate species and the first fish-like vertebrates first appeared in the fossil record. The greatest record of Cambrian animal fossils, including soft-bodied creatures, may be found in the Burgess Shale. The Paleozoic era's Cambrian phase saw the most rapid explosion of evolution ever recorded. A staggering diversity of life, including many of the main animal groupings still extant today, emerged during the Cambrian Explosion. The chordates, which include vertebrates (animals with backbones) like humans, were among them. According to some experts, the appearance of predators was made possible by a slight, possibly transient increase in oxygen that abruptly crossed an ecological threshold. Carnivory's emergence would have sparked an evolutionary arms race that produced the explosion of various body kinds and behaviours that now populate the oceans. The team comes to the conclusion that a scarcity of oxygen and toxic hydrogen sulphide killed off a large number of Cambrian species. It is believed that similar circumstances led to the devastating Permian extinction 251 million years ago. According to Gill, there were multiple instances of fast extinction in the second half of the Cambrian.

How do distance and displacement differ in this situation​
mr_godi [17]

Answer:

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

Megafires are high-intensity, uncontrollable fires that cover more than
julia-pushkina [17]

Megafires are high-intensity, uncontrollable fires that cover more than firestorms.

Storms occur when heat from wildfires creates its own wind system. This phenomenon can lead to very strange weather effects. An active Zaca Fire flame front in Santa Barbara County, California. This 2007 fire was one of the largest on record in California.

  • A very intense and destructive fire, usually accompanied by strong winds. Roose's house and garden were destroyed in a 1991 Auckland storm.
  • Under certain conditions, many individual fires from a nuclear explosion can coalesce into one large fire known as a "firestorm". The combination of many small fires fans the flames by heating the air and forcing strong winds to blow inward toward the fire.

Desert winds blowing sands across the dunes involves what TWO systems?
Eddi Din [679]

Answer:

Geosphere and atmosphere.

Explanation:

Earth is a planet that has multiple systems, and even though all of them are unique with their own characteristics, they are all connected, influence each other, and depend on each other in many ways. Two of those systems or spheres are the geosphere and atmosphere, with the geosphere being represented by the crust, while the atmosphere is represented by the air above the surface of Earth.

In this case, we have desert winds blowing sands across the dunes. The desert winds, or any winds for that matter, are air masses, thus they belong to the atmosphere. The sands are sediments, thus they are formed from rocks that have broken apart, meaning that they belong to the geosphere. The conclusion is that the winds as being part of the atmosphere and sands being part of the geosphere create a situation where these two spheres interact with each other.
