Question

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?

Answer 1

Answer:

She will need approximate $50.24\ ft$ of plastic border

Step-by-step 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
