Answer 2

Answer:

$32.13km$

Step-by-step explanation:

First find the arc length of

$\frac{90}{360} \times2 \pi r \\ \frac{1}{4} \times 3.14 \times 9 \times 2\\ = \frac{254.34}{4} \\ = 14.13km$

Now let's find the perimeter

$perimeter = arc \: \: length + radius + radius \\ 14.13km + 9 + 9 \\ =32.13km$
