For this case we have to:

The circumference or perimeter of a circle is given by:

$c = \pi d\\$

where d is the diameter of the circle.

Substituting the given value of c,
c = 18.85m , we have:

$18.85 = \pi d\\$

$d = (18.85)/(\pi ) \\\\d = 6\\$

Therefore, the diameter of the circle is 6m.

Answer:

Option C
