Question

2.2 cu dm of lead is to be drawn into cylindrical wire 0.50 cm in diameter. find the length if the wire.

Answer 1

Answer:

112 m

Step-by-step explanation:  

Volume of wire = (2.2*10*10*10) cm^3

                           = 2200 cm^3.

22/7 * 0.25 * 0.25 * h = 2200

h = (2200 * 7/22 * 1/ 0.25*0.25) cm

Therefore

Length of wire = (11200/100) m = 112 m
