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.
