    Hint: Start by finding the coordinates of the center of the circle. If you don't know the standard form for the equation of a circle, you'll have to look it up.

    If you mean (x-h)^2+(y-k)^2=r^2
    i know it i just don't understand how i would get
    (x-3)^2 + (y-4)^2=25 thats what the back of my book tells me i just don't see how they get to it..

    That's the right general equation; Look up what h, k, and r stand for.
