If the copper is drawn into wire whose diameter is 6.50 mm, how many feet of copper can be obtained from the ingot? The density of copper is 8.94 g/cm3. (Assume that the wire is a cylinder whose volume is V=Ï€r2h, where r is its radius and h is its height or length.)

Answer:

The amount of copper that can be drawn from the inglot is 141.31ft & 7.50mm diameter.

Explanation:

150 lb = 68.039kg = 68039 g

Density = Mass/Volume

Volume = Mass/Density

Density = 8.94g/cm3

Volume = 68039/8.94= 7610.63 cm3

V = π(r^2)h;

r = 7.50mm = 0.75cm

h = V/(π(r^2))

h = 7610.63/(π (0.75^2))

h = 4307.09 cm = 141.31 ft.
