Answer:

circumference of a circle formula is C=2*pi*r

Explanation:

then

141.3 = 2*pi * r

solve for r

141.3/ (2*pi) = r

22.48859 feet

diameter is 2*r

2*22.48859= 44.9771 feet

divide by 3 because there are 3 feet in one yard

44.9771/3= 14.99239 yds.

it doesn't say to round off, but I would call this 15 yds.

Diameter is 15 yards ± .008 yds That's just about 1/4 of an inch
