Actually it is 10.504 which should be rounded to 11 inches.
The circumference of 9 inch diameter circle is about 28.27 inches.
The circumference of a circle with a 39 inch diameter is 122.52 inches.
circumference = pi * diameter so, diameter = 9/ pi = 2.86
The diameter of a 3-inch circumference is: 0.954 inches.
The diameter of a 60-inch circumference circle is 19.1 inches. (D = c divided by Pi)
The diameter of a circle that has a 33 cm circumference is: 10.5 cm (circumference divided by pi = diameter).
If the circumference of a circle is 33 feet, its diameter is: 10.5 feet.
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 6 inch diameter circle is: 18.8 inches. (diameter x Pi = circumference)
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
31.4 in
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
