Answer:

72

Step-by-step explanation:

Formula: A= 3.14r^2

4069.44^2 = 3.14r^2

(divide both sides by 3.14)

1296=r^2

(find sqr root of 1296)

36=r

to find the diameter with the radius, multiply radius by 2... 36*2= 72

The diameter of a pond with an area of 4069.44^2 is 72!

Hope this helps anyone :)
