The circumference is equal to pi ( 3.14167... ) times the diameter. You do the math.
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a diameter of 5 the circumference is: 31.4
The circumference of a circle with a diameter of 51m is: 160m
If a circle has a diameter of 2.25, the circumference is: 7.069
The circumference of a circle with a diameter of 25 is: 78.54
The radius is 1.9 inches.
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
The perimeter or circumference of a circle is pi x diameter where pi = 3.1416 The circumference of a 12 inch circle is 3.1416 x 12 = 37.699 inches so two 36 inch lengths will be required.
