Maximum value of $r$ can be approximately 70 yards.

Work Step by Step

The minimum value of $r$ can be $0$ because the radius cannot be negative and the maximum value of $r$ at $x=0$ is: $r_{0y.}=\dfrac{440-(2)(0)}{2 (3.14)}\approx 70.06$y. Thus, the maximum value of $r$ can be approximately 70 yards.
