The length around the rug is the circumference.

The formula is C = 2 x PI x r

C = 2 x 3.14 x 5 = 31.4 feet

For this case we must find the perimeter of the circular carpet.

By definition, the perimeter of a circle is given by:

[tex]P = 2 \pi * r[/tex]

Where:

r: It is the radius of the circle

According to the statement we have:

[tex]r = 5 \ ft[/tex]

Substituting:

[tex]P = 2 * 3.14 * 5\\P = 2 * 3.14 * 5\\P = 31.4 \ ft[/tex]

So, you need[tex]31.4 \ ft[/tex]

Answer:

[tex]31.4 \ ft[/tex]
