ĺ 6. A sphere of diameter 18 cm is dropped into a cylindrical vessel of diameter 36 cm partlyfilled with water. If the sphere is completely submerged, then find the water level rises(in cm) |

Answer» Volume of sphere= 4/3 x π x 9³ =972 π Volume of water in vessel= π x 18² x h = 324 π h New volume in vessel = Vol. of sphere + Vol. of water π x 18² x H = 972 π + 324 π h 324 H = 972 + 324 h (here in RHS and LHS π is common ) 324 H - 324 h = 972 H - h = 972/324 = 3 cm level of water rises by 3cm |
