Question

A piece of ductile metal is in the form of a cylinder of diameter 1 cm and length 11 cm. It drawn out into a wire of diameter 1 mm. What will be the length of wire so obtained. ​

Answer 1

Answer:

mark my answer as brainliest pls

Step-by-step explanation:

diameter of wire = 1 cm

radius = 0.5

length = 11 cm

now, volume = 8.653 cm

the volume of both will be the same.

now, the diameter of new wire = 1mm = 0.1 cm

radius = 0.05

; new length = volume/Лr² = 1100.02 cm = 11m
