Finding diameter

  1. Jan 20, 2007 #1
    1. The problem statement, all variables and given/known data
    A circle has 300 bases around it..each base being .36nm apart. What is the diameter in micrometers?

    2. Relevant equations
    C = pie x diameter

    3. The attempt at a solution
    .36nm x 300 bases = 108nm is the circumference

    108nm = pie x diameter

    108nm / pie = 34.4nm

    34.4nm x .001 micrometers = 3.44E-2

    Bases around circles? You'll really have to be a bit more specific, for the sake of everyone who wants to help.
