Given the circle has a radius of 64, to get the value of the radius,r we shall proceed as follows.
Area=πr^2
Thus;
64=πr^2
64/π=r^2
r^2=20.3718
r=sqrt(20.3718)
r=4.5135
Therefore the length of radius,r=4.5135 units

The other answer is the big wrong,

AREA: 64pi^2

r = (64pi/pi)^.5

r = 64^.5

r= 8


r = 8
