2. Area: 572.555261117
Circumference:84.8230016469
3. Area:283.528736986
Circumference:59.6902604182
4. Area:1017.87601976
Circumference:113.097335529
5. Area: 63.6172512352
Circumference: 28.2743338823
6. Area:380.132711084
Circumference:69.115038379
Step-by-step explanation:
The formula for the area of a circle is π*r^2, r being the radius or the half line in the circle, and the formula for the circumference is π*r*2, or π*d, or the diameter which is the line that goes all the way through like number 5. The radius is half the diameter.
For this case we have the following equation, in a linear way:
This expression can be written in the form 
Where "m" is the slope and "b" is the cut point with the y axis.
Rewriting the given expression we have:
Thus, the slope is 3 and the cut point is -5.
To graph, we must find two points through which the line passes, so, we perform the following steps:
Step 1:
We do 
Thus, the point 
Step 2:
We do
Thus, the point

Answer:
heyyy
Step-by-step explanation:
heyyyy im just here to help in getting them pts because im smart like that :)
Because in both graphs the shaded region is above the curve, the correct option is C.
<h3>
Which pair of inequalities is graphed?</h3>
On the graph we can see two parabolas, such that the y-intercepts of these are:
y = 6
y = -4
So we just need to find the pair of options with these y-intercepts, and noticing that for both cases, we must have:
y > parabola.
Because both shaded regions are above the parabolas.
The only option that meets these requirements is option C. Where there is a mistake, as you can see both curves have dashed lines, and always when we have dashed lines we should use the symbols > or <, while in that option we have a ≥ symbol
