Answer:
28.25 square units
Step-by-step explanation:
A circumference of the circle is
[tex]C=2\pi r,[/tex]
where r is the radius of the circle.
So,
[tex]18.84=2\pi r\\ \\r=\dfrac{18.84}{2\pi}=\dfrac{9.42}{\pi}\ cm[/tex]
The area of the circle is
[tex]A=\pi r^2[/tex]
Substitute the value of the radius:
[tex]A=\pi \cdot \left(\dfrac{9.42}{\pi}\right)^2=\dfrac{9.42^2}{\pi}\approx 28.25\ un^2[/tex]
