Ok. Thanks.You gave me more help then I wanted, but I was doing it backwards. So, if I originally left the 33pi^2 on the right and then divided out the square then I would of had the (2r-1)^2? This is where that square came from? Something like using a literal equation?We just started quadratic equations and this was the last question in my homework. Thanks a lot for your help, it is appreciated!
