The circumference of a circle with a 20.5 inch diameter is 64.4 inches.
Circumference=2.5 inches
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
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.
I assume you want the circumference which is pi times the diameter, so for 37 inch diameter the circumference would be about 116.24 inches.
