The diameter of a circle with a circumference of 29 feet is about: 9.231 feet.
Circumference = 29*pi 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.
Given a circle with a diameter of 4, the circumference is: 12.6 (diameter x Pi = circumference).
Circumference: 29*pi = 91.106 inches to 3 decimal places
circumference = Pi * diameterdiameter = circumference / PiThe diameter is 4/Pi or approximately1.2732490258705930933383273555459.
The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
12.5663706144, because the diameter (4) times Pi equals circumference
If a circle has a diameter of 4 bananas, it's circumference is 12.564 bananas
Circumference = pi*diameter so diameter = circumference/pi = 40/pi = 12.7324 feet (to 4 dp)
Circumference of circle: 4 times pi in inches
