A hemispherical vessel of radius 14 cm is filled fiuld with sand. This sand is poured on a ground. The heap of sand forms a conc shape of height 7 cm . Calculate the area of ground occupied by the circular base of the heap of the sand.

A hemispherical vessel of radius 14 cm is fully filled with sand . This sand is poured on a level ground. The heap of sand forms a cone shape of height 7 cm . Calculate the area of ground occupied by the circular base of the heap of the sand.

A cylindrical bucket , 32cm high and with radius of base 18cm , is filled with sand. This bucket is emptied on the ground and a conical heap of sand is formed . If the height of the conical heap is 24cm , find the radius and slant height of the heap.

Sand is pouring from a pipe at the rate of 12 cm^(3) /s. The falling sand forms a cone on the ground in such a way that the height of the cone is always one-sixth of the radius of the base. How fast is the height of the sand cone increasing when the height is 4 cm?

The bottom of a right cylindrical shaped vessel made from metallic sheet is closed by a cone shaped vessel as shown in the figure . The radius of the circular base of the cylinder and radius of the circular base of the cone each os equal to 7 cm . If the height of the cylinder is 20 cm and height of cone is 3 cm calculate the cost of milk to fill completely this vessel at the rate of Rs. 20 per litre.

The bottom of a light cylindrical shaped vessel made from metallic sheet is closed by a cone shaped vessel as shown in the figure. The radius of the circular base of the cylinder and radius of the circular base of the cone each is equal to 7 cm . If the height of the cylinder is 20 cm & height of the cone is 3 cm, calculate the cost of milk of fill completely this vessel at the rate of Rs. 20/liter.
