Answer:
169.56 ft.
Step-by-step explanation:
The formula for Circumference is simply:
C = π * D
Circumference equals Pi times diameter
Our diameter is 54, because diameter is just Radius times 2.
54 • Pi (first three digits, 3.14) = 169.56
Answer:
Option B. No, because the graph of the line connecting the ordered pairs does no pass through the origin.
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line<u><em> and the line passes through the origin</em></u>
step 1
Connect the ordered pairs of the graph
The y-intercept is the point (0,20)
see the attached figure
That means, that the line not passes through the origin
therefore
The relationship between the two quantities is not proportional
