Answer:
1 unit
Step-by-step explanation:
The circumference of a circle can be found by multiplying the diameter by pi (around 3.14)
[tex]c = \pi \: d[/tex]
If you rearrange this equation to find the diameter, you get:
[tex]d = \frac{c}{\pi} [/tex]
If you add your numbers into this, you get:
[tex]d = \frac{3.14}{\pi} [/tex]
As pi is around 3.14, you essentially end up with d = 3.14/3.14, and because any number divided by itself is equal to 1, we end up with the diameter being 1.
