<em>361</em><em>π</em><em>km²</em>
<h2>
<em>Explanation</em></h2>
• the formula to find the area of a circle is A=πr²
<h3> =>
<em>A=π(19km)²</em></h3><h3>
<em>A=π(19km)² => A=361πkm</em>²</h3><h2>

It passes through the center of the points. (2)
When doing a line of best fit, you want the line to have equal number of points on either side of the line.

Answer:
x = 7
Step-by-step explanation:
You solve a linear equation by putting the variable on one side of the equal sign and a constant on the other side. Here, variables and constants are on both sides of the equal sign, so you need to separate them.
The basic idea is that you add the opposite of any term you don't want. Whenever you perform any operation (like "add"), <em>you must do it to both sides of the equation</em>.
We observe that x-terms have coefficients of 10 and 9. We choose to add the opposite of 9x to both sides:
10 -9x -5 = 9x -9x +2
x -5 = 2 . . . . simplify
Now, we still have -5 on the left, where we don't want it. So, we add its opposite (+5) to both sides:
x -5 +5 = 2 +5
x = 7 . . . . simplify
The solution is x = 7.

<em>Additional comment</em>
If we were to end up with an x-coefficient other than 1, we would divide both sides of the equation by that coefficient. This will leave the x-term with a coefficient of 1.
36 of them did not have an umbrella because out of 11 people, 4 did not bring an umbrella.
First, put your polynomial in standard form(ax²+bx+c=0). Then plug the a,b and c for x=(-b+-√b²-4ac)÷2a. As a result, you can either get one, two or no real answers.
