Answer:
C. Region B
Step-by-step explanation:
Since you already have the graphs of the lines, you only need to shade the proper area.
For the first equation, since y is less or equal than x-2 you have to shade the bottom part of the line.
For the second one, since y is more or equal to 1/4x+4 you have to shade the upper part of the line.
The answer is the region where the to shaded parts intersects each other.

Answer:
area=38.465, circumference=21.98
Step-by-step explanation:
Divide the diameter by 2 to find the radius
7/2=3.5
Use the formula πr^2 find area
3.5*3.5=12.25
12.25*3.14=38.465
a=38.465
Then, use the formula 2πr to find circumference
2*3.14=6.28
6.28*3.5=21.98
c=21.98
36 of 90% is 35.4 Hope it helps
