The perimeter C of a full circle is given by:

$C=2\pi R$

where R is the radius.

We're given that:

R = 8.9 inches

π = 3.14

So, we get:

$C=55.89\text{ inches}$

However we need the perimeter of a quarter circle. We have to divide our answer by 4.

$C=13.97\text{ inches}$

And that's our final answer.
