We have been given some information about a circle whose area is 13266.5 square yards. And we are advised to use value of π =3.14.

Now we need to find the radius of the circle so we can use formula of area of the circle which is :

[tex] Area = \pi r^2[/tex]

[tex] 13266.5 = 3.14 r^2[/tex]

[tex] \frac{13266.5}{3.14} = r^2[/tex]

[tex] 4225 = r^2[/tex]

take square root of both sides

65 = r

Hence final answer is radius of the circle = 65 yards.
