To find the circumference of a circle, use the formula C = 2πr where π is 3.14 and r is the radius. Since diameter is given and not radius, convert diameter into radius. The formula to convert diameter to radius is d= 2r. Substitute the value of diameter using the formula d= 2r.
> d= 2r
> 1/6= 2r
Divide both sides by 2
> 1/6 /2= 2r/2
> 1/12= r
Now, substitute the value of r using the formula C = 2πr
> C = 2(3.14)1/12
> C = (3.14)1/6
> C = 0.5233 yards.
