Explanation:

Step1: Find the radius from the circumference

The formula for the circumference of a circle is \(C = 2\pi r\). Given \(C=18.84\) mm, we solve for \(r\):
\(r=\frac{C}{2\pi}=\frac{18.84}{2\times3.14}\)
\(r = 3\) mm.

Step2: Calculate the area of the circle

The formula for the area of a circle is \(A=\pi r^{2}\). Substitute \(r = 3\) into the formula:
\(A=3.14\times3^{2}=3.14\times9 = 28.26\) square millimeters.

Answer:

\(28.26\)
