Answer:

Area,
$A=(81\pi )\ cm^2$

Explanation:

Given that,

The diameter of the circle, d = 18 cm

The radius of a circle is half of its diameter, r = 9 cm

The formula to find the area of a circle is given by :

$A=\pi r^2$

When r = 9 cm

$A=\pi (9\ cm)^2$

$A=(81\pi )\ cm^2$

So, the area of the circle is
$(81\pi )\ cm^2$ . Hence, this is the required solution.
