## Carissa15 one year ago Find the radius and height of the largest cylinder that can be inscribed in a sphere of given radius R. Can anyone help me with this please?

|dw:1441466638081:dw| |dw:1441467881519:dw| check for maxima ,then find r,and 2h

woah, thank you.

I now have $r^2=R^2- \frac{ h^2 }{ 4}$ what is the easiest way of "removing" the squared and obtaining r on it's own?
