Answer:

$1.57\textrm{ yd}$

Explanation:

Given:

Diameter of the circle,
$D=18\textrm{ in}$ .

We need to convert the diameter in yards.

We know that,
$36\textrm{ in} = 1\textrm{ yd}$

So,
$1\textrm{ in} =(1)/(36)\textrm{ yd}$

Now,
$18\textrm{ in} =(1)/(36)* 18=0.5\textrm{ yd}$

Circumference of a circle of diameter,
, is given as:

$\textrm{Circumference}=\pi D$

Plug in 0.5 for
and calculate the circumference. This gives,

$\textrm{Circumference}=\pi * 0.5=3.14* 0.5=1.57\textrm{ yd}$

Therefore, the circumference of the given figure is
$1.57\textrm{ yd}$ .
