A cylindrical tin 8cm in diameter contains water to depth of
4cm.If a cylindrical wooden rod 4cm in diameter and 6cm long is
placed in the tin it floats exactly half submerged.what is the New depth
of water
4cm.If a cylindrical wooden rod 4cm in diameter and 6cm long is
placed in the tin it floats exactly half submerged.what is the New depth
of water
volume of wooden rod = π(2^2)(6) = 24π
volume which is submerged = 12π
So the volume in the cylinder will change by that amount
π(4^2)h = 12π
16h = 12
h = 12/16 cm = 3/4 cm
new depth = 4+3/4 cm = 19/4 cm or 4.75 cm
volume which is submerged = 12π
So the volume in the cylinder will change by that amount
π(4^2)h = 12π
16h = 12
h = 12/16 cm = 3/4 cm
new depth = 4+3/4 cm = 19/4 cm or 4.75 cm
Thanks a lot
