# Math Help - IN THE EQUATION C= 6.3r , which is the independent variable and which is the dependen

1. ## IN THE EQUATION C= 6.3r , which is the independent variable and which is the dependen

IN THE EQUATION C= 6.3r , which is the independent variable and which is the dependent variable ? (C= circumference, r= Radius

Please help guys, am gonna have this on my math test tomorrow, but i cannot find a answer !

2. Does one influence the other in this case.

I would put r on the independent axis. I wouldn't say either is actually dependent.

3. If I were to choose between Circumference and radius, I would most likely choose radius as the independent, but the question can be interpreted either way.

4. Generally speaking if you have an equation like "y= f(x)" so that y, alone, on one side of the equation, is equal to a function of x, then y is the "dependent variable" and x is the "independent variable".
