    Need help with a calculus question

    Question is - Find the dimensions of the cylindrical can of greatest volume that can be made from 150pi squared cm of sheet aluminium. I solved that h=75-r^2/r and when I differentiated it, the equation came out as -2-(75-r^2)/r^2 and no matter how much I tried, I just couldn’t get r. I know that it equals 5, but I have absolutely no idea how the textbook got there
