Explanation:
The figure shows a regular pentagon with the radius and the length of one side given. The Pythagorean theorem to find the missing side of the right triangle whose given sides are the pentagon radius and half the side length. That missing side is the apothem of the pentagon. As with any regular polygon, the area of this pentagon will be half the product of the perimeter and the apothem. The perimeter of a pentagon is 5 times the side length. All dimensions are in feet, so the area will be in square feet.

<em>Additional comment</em>
The working out was not requested, but here it is, anyway.
a = √(40.8² -(48/2)²) = √1088.64 ≈ 32.99 . . . feet
P = 5(48 ft) = 240 ft
A = (1/2)Pa = (1/2)(240 ft)(32.99 ft) = 3959.3 ft²
Note that the radius has been rounded down to the nearest tenth. If the full-accuracy value were used, the area would be found to be 3963.98 ft².
It would be classified as the lithosphere.
numbers or miles or feet.
The first thing to say is that there are two geographical features with the same name: the Rocky Mountain System and the Rocky Mountains (s.s.) that are part of it.The complete orographic system is something like a very varied sample of geological and tectonic processes.The system extends for more than 2982 miles, from Canada to the southern United States, (state of New Mexico). Its transverse extension varies between 68 and 300 miles, with the eastern edge being very close to Denver, and constituting a prominent feature within the central plains of the continent.The far west is not far from Salt Lake City, Utah, and is separated from the Sierra Nevada, Cascade, and Coastal chains-farther west-by the Great Basin and the Columbia River Plateau.The Rocky Mountains end before entering Alaska, not the System that contains them, which is also known to include the highest peaks in North America. In the United States, the highest height is recorded at Mount Elbert in Colorado, showing 4,401 m.s.n.m.Also in the Rocky Mountains is the watershed of the continent, which obviously separates the basins that drain towards the Pacific from those that drain towards the Atlantic.
As a peninsula, the people of Greece took advantage of living by the sea. The mountains in Greece did not have fertile soil good for growing crops, like in Mesopotamia, but the mild climate allowed for some farming. The Greeks, like many other ancient civilizations, felt deeply connected to the land they lived on.
I hope that helps you. :)
