Direct variation problems are solved using the equation y = kx. In this case, you should use d for distance and f for force instead of x and y. Step 2: Use the information given in the problem to find the value of k. In this case, you need to find k when f = 160 and d = 5.
Interpretation according to the definition of direct variation: When the radius (the independent variable) is doubled, the circumference (the dependent variable) is also doubled. This is how the relationship of the variables C (circumference) and r (radius) is described in direct variation. I hope that you realize that it's not just y=kx. If you know the key phrases and the definition (and the relationship), you can solve real-life situation problem involving direct variation.
