An open metal bucket is in the shape of a frustum of a cone, mounted on a hollow cylindrical base made of the same metallic sheet. The diameter of the two circular ends of the bucket are 45 cm and 25 cm . the total vertical height of the bucket is 40 cm and that of the cylindrical base is 6 cm . Find the area of the metallic sheet used to make the bucket, where we do not like into account the handle of the bucket. Also, find the volume of water the bucket can hold, in litres.

Hanumappa and his wife Gangamma are busy making Jaggery out of sugar-cane. They have processed the sugar cane juice to make the molasses which is poured into moulds of the shape shown in the figure. It will be cooled to solidify in this shape to be sent to the market. Each mould is in the shape of a frustum of a cone having the diameters of its two circular ends as 30cm and 35cm and the height of the mould is 14cm. If each cm^3 of molasses weighs about 1.2gm, find the weight of molasses that can be poured into each mould (Take π=22/7)
