If sum of radius and height of a cylinder is 6, then ist maximum volume is

If the sum of radius and height of a solid cylinder is 20 cm and its total surface area is 880 cm^2 then its volume is:

The sum of radius of the base and height of a cylinder is 37 m. If the total surface area of the cylinder is 1628 m^(2) , find the curved surface area and volume of the cylinder

The sum of radius of base and height of a solid cylinder is 37 cm. the total surface area of the solid cylinder is 1628 cm^(2) . Find the volume of the cylinder.

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

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

A cylinder is inscribed in a sphere of radius r What is the radius of the cylinder of maximum volume ?
