1. Radius $= 12 m$
2. Diameter $= 18 i n$
The formula for the radius of a circle with area r is

Area $= π r^{2}$
The circle's radius is $= 12 m$
Area of the circle $= π r^{2}$
$= π \cdot 122$
$= 452.39 m^{2}$
Then, the area of the circle is $452.39 m^{2}$ . The diameter of the circle, $2 r = 18 i n$
The radius of the circle, $r = \frac{18}{2} = 9 i n$
Area of the circle $= π r^{2}$
$= π \cdot 9^{2}$
$= 452.39 m^{2}$
Hence, the area of the circle is $254.47 i n^{2}$ .
