AnswEr :
1100cm.
A piece of ductile metal is in the form of a cylinder of diameter 1 cm and length 11 cm. It's drawn out into a wire of diameter 1 mm.
The length of the wire so obtained.
Let the the length of the wire be R
Then;
→ Radius of cylinder =
→ Radius of Wire =
Formula use :
Thus,
The length of the wire so obtained is 1100 cm.
