Density of Lithium Metal: Calculate with D=m/V

[Faiien]

Homework Statement

What is the density of lithium metal in g/cm^3 if a cylindrical wire with a diameter of 2.40mm and a length of 15.0cm has a mass of 0.3624g?

Homework Equations

D=m/V

The Attempt at a Solution

The problem I'm having is I don't understand what the problem is asking. How do you calculate the density of lithium metal with the diameter/length of a cylindrical wire and a the mass of the wire.
