Someone plz help me i don't know the answer

DochEvi [55]

Since the problem is asking for the amount of braid to go AROUND the circular rug, we want to use circumference.

The circumference is calculated as pi * d, where d is the diameter.

The diameter given is 5, so the answer is 5 * pi which is about 15.7 or about 16 feet.
