Hanumappa and his wife Gangavva are busy making Jaggery out of sugar-cane. They have processed the sugarcane juice to make the molasses which is poured into moulds of the shape shown in Fig 16.72. It will be cooled to solidify in this shape to be sent to the market. Each mould is in the sh ape of a frustum of a cone having the diameters of its two circular ends as 30 cm and 35 cm and the height of the mould is 14 cm. If each c m^3 of molasses weighs about 1.2 gm, find the weight of molasses that can be poured into each mould (Take pi=22//7 )
