Question 901027: The weight of copper is 560 lbs per cubic foot. an AWG #4 copper wire is cylindrical in nature, has a diameter of 0.2043 inches and a length of 100ft. What is the cost of raw copper to produce such wire if copper is worth $5.40 per kg. (hint: V = π*r^2*h)
solve to the nearest cent

Try it this way:
p = 5.40 dollars per kg
D = 560 pounds per cubic foot
r = 0.2043/12 feet
h=100 feet
Additionally, use a conversion ration, K = 0.454 kilograms per pound

You want COST of the piece of copper described.

using the additional conversion factor for kilograms from pounds. Substitute the given listed values and compute the cost.

This may seem clearer:
dollars.
