For this case we have to:
The circumference or perimeter of a circle is given by:
[tex]c = \pi d\\[/tex]
where d is the diameter of the circle.
Substituting the given value of c, [tex]c = 18.85m[/tex], we have:
[tex]18.85 = \pi d\\[/tex]
[tex]d = \frac{18.85}{\pi } \\\\d = 6\\[/tex]
Therefore, the diameter of the circle is 6m.
Answer:
Option C
