To find the radius given the circumference of a circle, we first have to divide the circumference by pi, or an estimation of 3.14. This will give us the diameter.
Since we know that the radius of a circle is simply half the diameter, we divide the number we got from the problem above by 2. This will give you your answer!
I believe you just add all the widths together which would give you 12 feet and 28 inches or 4 yards and 4 feet and 4 inches wide. Hope this helps you.
