Answer:

The total length of border was
$31.4\ yd$

Explanation:

we know that

The length of the border would be the circumference of the circle,

The circumference of the circle is equal to

$C=2\pi r$

In this problem we have

$r=5\ yd$ -----> given problem

substitute

$C=2\pi (5)=10\pi\ yd$

assume

$\pi=3.14$

$10\pi=10(3.14)=31.4\ yd$
