Curved surface area of a right circular cylindrical log of wood of uniform density is 440 sq`*`dcm. If 1 cubic dcm of wood weight `1*5` kg and weight of the log is `9*24` quintals, then calculate the length of diameter of log and its height.

If the surface area of a right circular cylindrical pillar is 264 sq-metres and volume is 396 cubic-metres, then calculate height and length of diameter of this pillar.

The curved surface area of a solid right circular cylinder is 1,320 sq.cm. If the length of base diametre of the cylinder is 14 cm then find the height of the cylinder.

The curved surface area of a right circular cone is 1.76 m^(2) and its base diameter is 140 cm. What is the height of the cone ?

Height of a hollow right circular cylinder, open at both ends, is 2*8 metres. If length of inner diameter of the cylinder is 4*6 dcm and the cylinder is made up of 84*48 cubic-dcm of iron, then calculate the length of outer diameter of the cylinder.

The volume of the greatest sphere that can be cut off from a cylindrical log of wood of base radius 1 cm and height 5 cm is

The curved surface area of a right circular cone is sqrt(5) times of its base area . Find the ratio of the height and the length of radius of the cone.

The volume of the greatest sphere that can be cutt off from a cylindrical log of wood of base radius 1 cm and height 5 cm is__

If the curved surface area of a solid right circular cylinder of height h and radius r is one-third of its total surface area, then h = (1/k)r, find k.

The lower part of a toy is right circular cylinderical and its upper part is conical. The diameter of its base is 8 cm and height of the cylindrical part is 5 cm. If the total height of the boy is 8 cm, find the area of the curved surface and its volume (pi=3.14)
