The diameter of a circle who's circumference is 28.26 miles is: nine (9) miles
To find the diameter of a circle with a 9-inch circumference, you can use the formula for circumference: C = πd, where C is the circumference and d is the diameter. In this case, C = 9 inches. Rearranging the formula to solve for the diameter, you get d = C / π. Substituting in the known values, the diameter of a circle with a 9-inch circumference is approximately 2.87 inches.
The circumference of a circle is the perimeter of the circle for a given diamater.
The circumference of a 36 circle is: 113.1 (diameter x pi = circumference).
