Answer:
3 miles
Step-by-step explanation:
The circumference of a circle can be found using:
c=[tex]\pi d[/tex]
We know the circumference is [tex]3\pi[/tex], so we can substitute that in for c
[tex]3\pi[/tex]=[tex]\pi d[/tex]
We want to find the diameter. To do this, we need to get d by itself. It is being multiplied by pi. To undo this, divide both sides by pi. This will cancel pi, and leave d by itself.
[tex]3\pi /\pi =\pi d/ \pi[/tex]
3=d
So, the diameter is 3 miles
