Circumference = 18.84 units
To find the area of a circle, you need radius r.
First, you calculate the radius from the circumference.
[tex]\begin{gathered} \text{Circumference = 2 }\pi\text{ r} \\ 18.84\text{ = 2 }\times\text{ 3.14 }\times\text{ r} \\ 18.84\text{ = 6.28r} \\ r\text{ = }\frac{18.84}{6.28} \\ r\text{ = }3\text{ units} \end{gathered}[/tex]Next, find the area.
[tex]\begin{gathered} \text{Area = }\pi r^2 \\ =\text{ 3.14 }\times3^2 \\ =\text{ 3.14 }\times\text{ 9} \\ =\text{ 28.26 square units} \end{gathered}[/tex]
