Diameter = Circumference/pi = 1.91 inches, approx.
Circumference = 37.7 inches Diameter = 12 inches
A circumference of 66.76 inches.
The circumference of a 6 inch diameter circle is: 18.8 inches. (diameter x Pi = circumference)
The circumference of a six-inch diameter circle is: 18.8 inches.
The circumference of 9 inch diameter circle is about 28.27 inches.
The circumference of a circle with a 20.5 inch diameter is 64.4 inches.
The circumference of a circle with a 39 inch diameter is 122.52 inches.
The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
circumference = pi*diameter so diameter = circumference/pi = 4.456 inches

The equation for circumference is Pi(diameter), so the exact value of the circumference of a tire with a 29 inch diameter is 29pi.
circumference = pi * diameter so, diameter = 9/ pi = 2.86
The circumference is equal to the diameter multiplied by pi. Therefore, if you know the circumference, you can divide by pi to get the diameter.
Please divide the circumference by pi, to get the diameter.
