Getting the central area of a polygon is not possible. Probably the question refers to the central angle. In a a regular polygon, getting the central angle is that you need to use the formula.
Central Angle of a polygon = 360 degrees / number of sides of a polygon.
Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.
Area of the circle is the area covered by that circle. The area of the circle whose circumference is 7π m is 12.25π m².
<h3>What is the area of a circle?</h3>
The area of the circle is the area covered by that circle. It is given by the formula,
where r is the radius of the circle.
As it is given that the circumference of a circle is 7π m. Therefore, the radius of the circle can be written as,
Now, we know the formula of the area of a circle, therefore, the area of the circle can be written as,
Hence, the area of the circle whose circumference is 7π m is 12.25π m².

The sample space is all of the possible combinations using the stuff given. For example, you can make a ham and rye sandwich, a ham and sourdough sandwich, and a ham and white sandwich, and so on.
Answer:
c = 27
Step-by-step explanation:
If c divided by 9 equals to 3, then the other way around would be 3 times 9 equals to c, which is how you would get 27. If you look at PEMDAS, multiplication and division are together and work the other way around when used with each other, just like addition and subtraction.
I know this is kind of a lame answer with no fancy math words to back it but please, it's the best I could do.
