a cylindrical vessel 60cm in diameter is partially filled with water.a sphere 30cm in diameter is dropped into it.the increase in the level of water in the vessel is...?

• vol. of sphere = 4/3*pi *r^3 vol. of cylinder =pi *r^2* H
  now increase in vol. of cylinder = vol. of sphere
  since the radius of both sphere and cylinder are same,therefore
  4/3*pi *r^3 =pi *r^2* h where h is the increment in the level of water and r= 30 cm
  h= 40 cm

• ans 5cm
  
  vol of sphere = vol of water raised in the cylinder (water makes the shape of which in it is present)
  (4/3) * pi * (15)^3 = pi * (30^2) * h
  by solving we get h= 5cm
