Answer:

She will need approximate
50.24\ ft of plastic border

Explanation:

we know that

The circumference of a circle is equal to


C=2\pi r

In this problem we have


r=8\ ft

substitute


C=2\pi (8)=16 \pi\ ft ----> exact value of the length of plastic border

assume


\pi=3.14


16 (3.14)=50.24\ ft ---> approximate value of the length of plastic border
