: : : : IF the cylinder of largest possible volume is inscribed in a given sphere, ratio of the volume of the sphere to that of the cylinder is?
: : : : I know the answere is 3^(1/2):1
I think an easer way is to write the radius of the cone rc as:
rc2=rs2-h2/4
where rs is the radius of the sphere.
Then the volume of the cone is
Vc=pi(rs2-h2/4)h
Then do the standard
Dh(Vc)=0 and solve for h. Then plug in to your
volume ratio.
