Hey there!
An equation has a proportional relationship if it fulfills the following:
-Is a linear function, meaning that is is graphed as a line all the way across a graph.
-It goes through the origin. So the point (0,0) has to be one solution to the equation.
That is how you can identify a proportional relation, a linear equations passing through the origin.

Hope this helps!

Make r the subject of the formula: V=πr²h
drek231 [11]
This is called a literal equation, or an equation with multiple variables. You solve it the same as you solve any other equation, but the variables stay there the whole time.

If they want "r" to be the subject, then they want you to solve for r. This means that you need to get the variable r by itself on one side of the equation, but still have the equation be equivalent to it original form.

     I'm going to show you, in steps, how to solve this problem:

<span>V=πr²h

Divide both sides by "</span>π²h<span>"
</span>V/π²h=(πr²h)/<span>π²h
</span>
V/(π²h)=r

Your answer is r=V/<span>π²h</span>
