# Q. 9.     The adjoining figure represents a rectangular lawn with a circular flower bed in the middle. Find:              (iv) the circumference of the flower bed.

We know that circumference of the circle is = $2 \pi r$
$\Rightarrow 2 \pi r = 2 \times 3.14 \times 2 = 12.56 \ m$
Therefore, the circumference of the flower bed with radius 2 m is  $12.56 \ m$
