Answer:

the area of the circle is
$2.25\pi\ cm^2$ .

Explanation:

We have,

Circumference of a circle is 3π cm

Formula of circumference of a circle is given by :

$C=2\pi r$

r is radius of circle

$r=(C)/(2\pi)\\\\r=(3\pi )/(2\pi)\\\\r=1.5\ cm$

Area of a circle is given by :

$A=\pi r^2\\\\A=\pi (1.5)^2\\\\A=2.25\pi\ cm^2$

So, the area of the circle is
$2.25\pi\ cm^2$ .
