Thermal expansion, percent change in density problem

  1. Oct 25, 2008 #1
    1. The problem statement, all variables and given/known data

    When the temperature of a metal cylinder is raised from 0.0°C to 100°C, its length increases by 0.23%. Find the percent change in density.

    2. Relevant equations
    ∆L = L∆T

    3. The attempt at a solution

    I don't have any real idea how to start the problem. How do I relate the change in length to the change in volume? I know that mass is constant.

    How do you find the volume of a cylinder? Hint: All linear dimensions increase by the same percentage.
