What is the area of the square? Help me pls
Allushta [10]

Answer and Step-by-step explanation:

First, we need to find out the circumference of the circle.

We know that the circle has a radius of 1, and that we are finding the circumference. We'll use the circumference equation of a circle.

2\pir

<u>Plug in 1 for r.</u>

2\pi (1) = 2\pi = circumference of circle

<u>Now, multiply the answer (the circumference) by 4 to get the perimeter of the square.</u>

<u />2\pi x 4 = 8\pi = perimeter of square

<u>Now, divide the perimeter by 4 to get what the side of the square is.</u>

<u />8\pi ÷ 4 = 2\pi

<u>Now, multiply </u>2\pi<u> by </u>2\pi<u> (side times side) to get the area.</u>

2\pi x  2\pi = 4\pi

The answer is A. 4\pi

Allisa [31]

Answer:

Types of polygon

Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon.

Regular and irregular polygons

Interior angles of polygons

To find the sum of interior angles in a polygon divide the polygon into triangles.

Irregular pentagons

The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°.

Example

Calculate the sum of interior angles in a pentagon.

A pentagon contains 3 triangles. The sum of the interior angles is:

180 * 3 = 540

The number of triangles in each polygon is two less than the number of sides.

The formula for calculating the sum of interior angles is:

(n - 2) * 180  (where n is the number of sides)
