Radius of bigger cylinder = 12 cm, height of bigger cylinder = 220 cm
Radius of smaller cylinder = 8 cm, height of smaller cylinder = 60 cm
Volume of bigger cylinder
=πr2h
=π×122×220
=31680 π cm3
Volume of smaller cylinder
=πr2h
=π×82×60
=3840π cm3
Total volume
=31680π+3840π
=35520π cm3
Mass=Density×Volume
=8×35520π
=892262.4 gm (1000gm =1kg)
=892.3 kg
