mass = volume x density
You know mass and density; solve for volume of the wire
Then volume of wire = pi*r^2*length
Solve for pi*r^2 = area
A 4.1089 g piece of aluminum wire with a circular cross section is 42.06 cm long and has density of 2.6989 g/cm3.
What is the volume of the wire and the cross sectional area of the wire in cm2?
