Hello!

We must use a certain formula to find the circumference of any circular thing. The formula is:

C = 2 * pi * r

We know that pi is 3.14, and the radius is 4.5 feet. Substitute and solve step by step:

C = 2 * 3.14 * 4.5

C = 6.28 * 4.5

C = 28.26

Don't forget to add the units!

ANSWER:

The circumference of the rug is 28.26 feet.
