Surface areas and volumes in one shot

If the surface area of an open cylinder is 100 cm^(2) , prove that its maximum volume will be 1000/(3sqrt(3pi) cm^(3) .

The difference between the outer and the inner curved surface areas of a hollow cylinder, 14cm long, is 88sq. cm. Find the outer and the inner radii of the cylinder, given that the volume of metal used is 176cu.cm.

The radius and height of a cylinder are equal. If the radius of the sphere is equal to the height of the cylinder, then the ratio of the rates of increase of the volume of the sphere and the volume of the cylinder, is
