A tin maker converts a cubical metallic box into 10 cylindrical tins. Side of the cube is 50 cm and radius of the cylinder is 7 cm. Find the height of each cylinder so made if the wastage incurred was 12%. `(pi = 22/7)`

Curved surface area of a cylinder is 440 cm^(2) and the radius of its base is 7 cm. Find the height of the cylinder.

Curved surface area of a cylinder is 8800 cm^(2) and the radius of its base is 7 cm . Find the height of the cylinder.

If radius is 7 cm and height is 10 cm, then what is curved surface area of cylinder?

A cylindrical tub of radius 5 cm and length 9.8 cm is full of water. A solid in the form of right circular cone mounted on a hemisphere is immersed into the tub. The radius of the hemisphere is 3.5 cm and height of cone outside the hemisphere is 5 cm. Find the volume of water left in the tub. ("Take "pi=22/7)
