hiii!!!
here's ur answer...
ATQ,
66cm³ of silver is drawn into a wire.
given the diameter of the wire is 1mm.
therefore radius of the wire = 0.5mm
66cm³ = 6600m³
therefore πr²h = 6600mm³
==> 22/7 × 0.5² × h = 6600mm³
==> 22/7 × 0.25 × h = 6600mm³
==> 5.5/7 × h = 6600mm³
==> h = 6600/1 × 7/5.5
==> h = 1200 × 7
==> h = 8400mm
in cm = 8400/10
= 840cm
hence, the length of the wire is 740cm.
hope this helps..!!
