Answer:
9π OR 28.26
Step-by-step explanation:
The formula for circumference is C = 2πr.
Substitute circumference = 18.84 for C.
18.84 = 2πr
Work backwards to find the radius of your circle.
r = 3
Now, use the formula for the area of a circle: A = π
.
Substitute r = 3 into the equation:
A = π 
= 9π ≈ 28.26

Answer:
2(187 + 241r)
Step-by-step explanation:
Answer:
It is a vertical line
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(1 - 9) / (-7 + 7)
-8/0
= undefined
Dividing by 0 gives you an undefined number. This means that the slope is undefined, and the line is a vertical line.
