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.
Answer:
Option (B)
Explanation:
The fault usually refers to the planar type of fractures that occurs in the earth's crust. Those faults in which the hanging-wall (H.W) block goes down with respect to the foot-wall (F.W) block is considered as the normal fault. This type of fault occurs due to the tensional force or extensional force.
Here, the rocks move in the opposite direction. This movement of blocks results in the release of a certain amount of energy that leads to the occurrence of shallow-focus earthquakes.
Thus, the correct answer is option (B).
It should be noted that a volcanic arc results from ridgeconvergent while tectonic movements and is associated with mid ocean ridge.
<h3>What is a volcanic arc ?</h3>
A volcanic arc can be regarded as a chain of volcanoes, which some miles long and it is usually formed above a subduction zone.
