Homework Statement
Find the volume of a right circular cylinder of maximum volume that can be inscribed in a sphere of radius 10cm.
I'm using this problem to help me solve a similar one with a cylinder inside a cone, now what I'm not sure about is, in the answer book they say, Let the radius of the cylener be r cm, 0 < r< 10. Then the height is 2sqrt(100-r^2)
... where did they get this height from?
