Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
If the circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.
The circumference c of any circle with diameter d is d X (pi). In this instance, 12 inches (3.14) = 38 inches, to the justified number of significant digits.
The circumference C = 2 r times pi C = 76 inches times pi. pi = 3.141592654...
The circumference of an 8-foot circle is: 25.13 feet.
