A solid right-circular cone of height 60 cm and radius 30 cm is dropped in a right-circular cylinder full of water of height 180 cm and radius 60 cm. Find

the volume of water left in the cylinder, in cubic metres. [Use pie = 22/7]



height of a cone=60cm,radius=30cm
volume of cone=1/3  \pi r x^{2} h
height of cylinder=180cm,radius=60cm
volume of cylinder= \pi r x^{2} h
remaining volume of water=volume of cylinder-volume of cone
                                                 \pi 60 x^{2} 180-1/3 \pi 30 x^{2} 60 cu.cm                              36 \pi x 18000-18000 \pi
                                                 18000(36 \pi - \pi )
                                                18000 x 35 x 22/7=1.98 cu.m
