Please help with this chemistry question...?

Question

Copper has a density of 8.96 g/cm^3. An ingot of copper with a mass of 57 kg (126 lb) is drawn into wire with a diameter of 9.50 mm. What length of wire (in meters) can be produced?

[ Volume of wire = (π)(radius)^2(length) ]

I tired but I'm just not sure if I got the right answer. I know you have to find the volume of the wire first and I'm not sure even I did that right.

Please show or explain how you get your answer the best you can..thank you so much!

Answer 1

vol = 57000 / 8.96

vol = π * 0.475^2 * l

57000/8.96 = π * 0.475^2 * l

l = 57000/8.96/π/0.475^2

l = 8974.60 cm = 89.75 m
