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.

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:
- An illustration showing how the landform changed
- A diagram showing cracks in the earth from an earthquake
- A computer model explaining the role of earthquakes in this landform change
Air rises at the equator, leading to low pressure and rainfall. Global atmospheric circulation creates winds across the planet and leads to areas of high rainfall, like the tropical rainforests, and areas of dry air, like deserts.
Answer: The Northern Hemisphere points towards the sun.
Explanation:
Summer solstice refers to two distinct times of the year, in either June the 20th or the 21st, when the Sun is farthest north in the Northern Hemisphere, and December 21st or the 22nd, when is farthest south in the Southern Hemisphere. During summer solstice in the northern hemisphere the one that gets more direct sunlight. It also signals the beginning of summer in the northern hemisphere and the start of winter in the southern hemisphere.
