Ariel has made a circular flower garden in her yard and she would like to put a plastic border around it. The garden has a radius of 8 feet. Which expression could be used to find the length (in feet) of plastic border she will need to put around her garden?

Respuesta :

Answer:

She will need approximate [tex]50.24\ ft[/tex] of plastic border

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

In this problem we have

[tex]r=8\ ft[/tex]

substitute

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

assume

[tex]\pi=3.14[/tex]

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