Rewriting Formulas

  1. Sep 26, 2006 #1
    On my homework, I was given the equation V=1/3 x pi x r squared x h. I need to rewrite the formula so that it is solved for h.

    Any help will be greatly appreciated!

    :uhh: You probably should have posted this in the homework section instead, and if you can't find the topic here later, it was probably moved there.

    But, I'm not mean. :tongue2:

    I'm not going to solve it for you, but think: If you do something to one side of the equals, the same thing has to happen on the other side.

    Use the 1/3 as an example, and cancel it by multiplying by 3. Then, just make everything else go to the other side by multiplying it over. ^:biggrin:

    I'm sorry about not posting this in the right forum...I just signed up today, so I'm still getting used to everything here!

    And about your reply...I tried what you said, and I got 3V over pi x r squared. Is this right??

    if you meant [tex] \frac{3V}{\pi r^2}[/tex] then yes

    Lol sorry...once again, I'm new here!

    Thank you both very much for your help. :biggrin:
