Answer:
C. The ratio of the area to the circumference is equal to half the radius.
Step-by-step explanation:
The area of a circle can be written as;
Area A = πr^2
The circumference of a circle is;
Circumference C = 2πr
Using the formula, w can derive the relationship between the two variables.
A = kC
k = A/C
Substituting the two formulas;
k = (πr^2)/(2πr) = r/2
So,
A = (r/2)C
A/C = r/2
The ratio of the area to the circumference is equal to half the radius.
Given;
Area = 200.96
Circumference = 50.24
Radius = 8
To confirm;
k = r/2 = 8/2 = 4
Also,
A/C = 200.96/50.24
A/C = 4

Answer:
So slope 1 would be positive
Slope 2 would be negative
Slope 3 would be zero
Step-by-step explanation:
If the slope is moving up from left to right, then it is positive
If the slope is moving down from left to right, then it is negative
If the slope is a vertical line and is not moving left/right, then it is undefined
If the slope is a horizontal line and is not moving up/down, then it is zero
So slope 1 would be positive because it is moving up from left to right.
Slope 2 would be negative because it is moving down from left to right.
Slope 3 would be zero because it is a horizontal line that is not moving up or down.
Hope this helped!
