Answer:

r = +(8 ft) / (√π)

Step-by-step explanation:

Formula for the area of a circle:  A = πr²

Here,                                     64 ft^2 = πr²

Solving for r², we get

        64 ft^2

r² = ---------------

              π

so that r is the positive square root of this expression:

                64 ft^2  

r = +sqrt ( -------------- )

                     π

 = +(8 ft) / (√π)
