    V = 2(pi)rh Divide by 2(pi)r on both sides V/2(pi)r = 2(pi)rh/2(pi)r V/2(pi)r = h h = V/2(pi)r

    what it is telling you to do is divide both sides of the equation by 2(pi)r to get the value of H

    Look how the equation is written and it explains how it is done

    that is how for these equations if you are trying to find the value the correct way should be how it is done!

    I have another question. Solve P = 2(l + w) for l. What are the missing values in the table? P w l 14 2 ? 22 8 ?

    Basically distribute the 2 with the l and w, so you end up with an equation of P = 2l+2w. Since you have the values for P and W, you can just plug them in, so the only term left would be "l". Does that make it more clear?

    all you have to do is move the constants to one side and make "l" by itself, that would be your solution to "l".
