Your answer is the last option
54-6i/41
First you want to get h alone so you divide 2<span>π</span>r by s so your answer would be
h=S/2πr
A proportional relationship is described by the equation
... y = k·x
The point (x, y) = (0, 0) is <em>always</em> a solution to this equation.
_____
In short, if the relationship is proportional, its graph will go through the origin. If the graph does not go through the origin, the relationship is not proportional.
___
Note that this is true if the domain includes the origin. You can have y = kx <em>for x > 10 </em>and the graph will <em>not</em> go through the origin because the function is <em>not defined</em> there.
16 dollars because it's 2 dollars per meter wide and it's 8 meters so 8x2=16
