A circle because if you cross-section it its like cutting it in half horizontally. So its like seeing it from the top view and you would see a circle.

Find the area of a regular octagon with a perimeter of 80 ft and an apothem of 12.07 feet

Finger [1]

Answer:

The area of a regular octagon with a perimeter of 80 ft and an apothem of 12.07 feet is 482.8 ft².

Step-by-step explanation:

An octagon is a polygon with eight sides. An octagon is regular (also called a regular octagon) is a polygon with all eight sides equal.

The apothem of a regular octagon is the shortest distance between the center and any of its sides, in other words, it is the distance that separates the center of the polygon from the central point of each side of the octagon.

The area is calculated using the following formula:

$Area=\frac{n*L*Ap}{2}$

Where:

n is the number of sides.
L is the length of one of the sides.
Ap is the value of the apothem.

Being n = 8 being an octagon and the perimeter P the sum of the sides of the octagon (P = 8 * L), the area of the regular octagon can be calculated by:

$Area=\frac{P*Ap}{2}$

In this case:

P=80 ft
Ap=12.07 ft

Replacing:

$Area=\frac{80ft*12.07ft}{2}$

Solving:

Area=482.8 ft²

The area of a regular octagon with a perimeter of 80 ft and an apothem of 12.07 feet is 482.8 ft².

If 2 - 3i is a solution to the equation x3 - 3x2 + 9x + 13 = 0, what are the other roots of the equation?

OLga [1]

The complex solutions come in pairs and the only difference between them is the sign between the real and imaginary part, so one of the other two solutions is $2+3i$ . The third solution can be easily found using the rational root theorem, and it's equal to -1.
