It's a horizontal line y = -9.
Look at the picture.
Answer: B.
I believe the correct answer is the last number line
In order to find the circumference, we first need to find the radius. We have the area, so we can find the radius. We set up this equation:

We begin by dividing both sides by pi.
483.76 =

Next, we take the square root of both sides to get the radius.
r = 22.
Next, we plug this into the formula for the circumference, 2 pi r

So, the circumference of this circle is 138.23 units.
We assume that we need to simplify the expression in two different ways.
Answer:
One way: Raise both, the numerator and denominator, to the third power, and then simplify the expression.
Second way: Simplify the terms inside parentheses, and then raise the result to the third power.
The result of both ways is the same: 
Step-by-step explanation:
<em>One way</em>
Raise both, the numerator and denominator, to the third power, and then simplify the expression:





This is the first simplification.
<em>Second way</em>
Simplify the terms inside parentheses, and then raise the result to the third power.
