Accepted Solution
A:
Hello!
We must use a certain formula to find the circumference of anything circular.
The formula is:
C = 2 Γ pi Γ r
We know that pi = 3.14 approximately and the radius is 3 feet.
Substitute:
C = 2 Γ 3.14 Γ 3
C = 6.28 Γ 3
C = 18.84 ft
ANSWER:
The circumference of the circular rug is 18.84 ft. (Last option)
