(Pi value = 3)

Given diameter of circle = 12 inches

Radius of circle :

$= \tt(diameter)/(2)$

$= \tt(12)/(2)$

$= \tt6 \: inches$

Thus, the radius of this circle = 6 inches

Circumference of this circle :

$= \tt2\pi r$

$=\tt 2 * 3 * 6$

$= \tt36 \: inches$

Thus, the circumference of this circle = 36 inches

The area of this circle :

$= \tt\pi {r}^(2)$

$=\tt 3 * 6 * 6$

$= \tt108 \: {inches}^(2)$

Thus, the area of this circle = 108 inches²
