I make it 6 cm diameter (well....5.97 cm really, but it depends how many places you take

#### Explanation:

You have been given density (d) and mass (m), so first you can determine volume (v).

Now you have the volume and the length (L) from which you can work out the cross sectional area,

Volume v =

So plugging in the numbers gives: D =
