A circular cylinder of internal diameter 8cm and height 10cm contain water to a depth of 6cm.Two solid lead sphere each of diameter 4cm are placed in it.Find height by which water level rises.
a)2cm
b)0cm
c)1cm
d)1 1/3

• volumn of cylinder is (pi*r^2*h), column of sphere is ( (4*pi*r^3)/3)
  r(sphere) = 2, so vol of 2 sphere is 64pi/3.
  r(cyclinder) = 4,
  pi * 4^2 * h = 64*pi/3
  so h = 4/3 = 1 1/3

• 1.33 so 1
  Total volume of sphere=33.52×2
  33.52×2=π×4^2×h ( rule of cylinder)
  h=1.33
