find the circular cylinder of greatest volume that can be inscribed in a right circular cone with altitude 20 cm and diameter of base 10 cm.

please answer in detail .....


so at a height h, the radius is 5(1-h/20)

check that.

VolumeCone= PIr^2 H
= PI h * 25(1-h/20)^2

find dV/dh, set to zero, solve for h.
