    Is that all you are given in the problem, or is there more?

    No, it is ok... right now, it is "solved" for C... you need to get "r" all by itself instead.

    If you divide both sides of the equation by 2pi, the right side simplifies to just "r"

    So its C-2pi=r ?

    whatever the vaue of r is put in that formula and pi has value 3.14

    if you don't have a value of r, that's fine... "solving for r" just means writing the expression down in a way where it starts like "r = "

    so, r = C / (2pi) is solving your original expression for "r"

    no, you don't subtract anything... don't let the 2pi term confuse you

    Think of easier stuff like this... if I said C = 5r, solve for r, you would divide both sides by 5, leaving you with C/5 = r, or you could just reverse it and answer r = C/5

    2pi is just some number... happens to be a little more than 6 since pi is about 3.14, but don't even worry about that.... just divide both sides by "2pi". On the r side, the 2pi divides out and "goes away" :)

    R = C / 2pi you divide C by 2pi, just like you divided (2pi)(R) by 2pi to get just R

    so, any equation like y = 2x can be rewritten by dividing both sides of it by the same thing... for example, divide both sides of y = 2x by 2..... y = 2 x (y/2) = (2x)/2 y/2 = x This starts with an expression of y and "solves it for x"

    you need the same idea with C = (2pi)R C = (2pi)R C/2pi = [ (2pi)(R) ] / (2pi) C/2pi = R <<<--- because the 2pi cancels out
