finding diameter

[anf9292]

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

correct?

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