That will depend on whether the 64 inches is the radius, diameter, or circumference of the circle.
The circumference of a circle if radius is 25 is about 157.1
The circumference of a circle with a 2pi radius is: 39.58
The radius of a circle with a circumference of 59 is: 9.39
If a circle circumference is 30 the radius is: 4.77
72" radius = 452 25/64 " circumference
Circumference=2Pir so 64 is Pixr and the radius is 64/Pi
That will depend on whether the 64 inches is the radius, diameter, or circumference of the circle.
If the circumference is 128 feet, the radius is 20.37 feet. If the diameter is 128 feet, the radius is 64 feet.
