Q. A hemispherical vessel of radius 7 m is filled with water. Find the amount of water (in litres) in the vessel.
(1000 litres = 1 m${}^3$)

Q. A hemispherical vessel of radius 7 m is filled with water. The amount of water in vessel is _____.(approx)
(1000 litres = 1 m${}^3$)

Q.

There are two vessels, A and B, each with a capacity of 100 litres. 80% of Vessel A is filled with milk and 90% of Vessel B is filled with water. The remaining portion of vessels A and B is empty. A milkman removed 25 litres of the milk from Vessel A and poured it into another Vessel C and then added 40 litres of water from Vessel B into it. He poured 40 litres of milk from Vessel A and 45 litres of water from Vessel B into Vessel D. Finally, he added the remaining water from Vessel B into Vessel A

It is known that the cost price of milk is Rs. $40$/litre. Instead of mixing the water from Vessel B, if the milkman adds the same quantity of mineral water into Vessel C, then what will the cost price of the mixture present in Vessel C? (Assume that the price
of mineral water is Rs. $20$/litre.)

It is known that the cost price of the milk is Rs. $40$/litre. If the contents of vessels C and D are mixed in the ratio of $1$ : $2$, then what is the cost of the resultant mixture?
(Assume that water is free.)
