Circumference is equal to the diameter multiplied by pi, or 3,14. Multiply 65 x 3.14.
If its circumference is 21.98 feet then its diameter is 21.98/pi = 7 feet rounded up.

A 128 inch circumference would imply a radius of 20.4 inches - a regular bicycle wheel, for example.
94/pi = 29.9211293 cm
Circumference is diameter times Pi, you do the math.
The circumference of the wheel is Pi multiplied by the diameter (0.705). Divide 1000 meters (1km) by that answer - and you'll have your solution !
If its circumference is 21.98 feet then its diameter is 21.98/pi = 7 feet rounded up.
11" Diameter x 3.145159 = 34.5575" Circumference 34.5575" Circum x 150 Revs = 5,183.6278" or 431.9689'
The wheel's circumference is: 219.9 centimeters.
Need to find:Distance wheel travels in 1 turn = circumference of wheelcircumference = π × diameter → diameter = circumference ÷ π333 ft ÷ 37 turns = 333/37 ft/turndiameter = 333/37 ft ÷ π ≈ 2.86 ft
radius=13 area=40.82 circumfrence=8.28025477707
5000 revolutions in 11000m = 1 revolution every 2.2m Circumference is 2.2m Circumference is diameter times pi 2.2m dividied by pi divided by 2 (to go from diameter to radius) = 35.014cm
The diameter of one bicycle wheel is 28 inches and its spokes run from the hub (or center) to the edge of the rim. The diameter of another bicycle wheel 21 inches. What is the difference in inches between the length of the spokes of the two wheels?pi * diameter = circumference, if that's what you're looking for. But be aware that the numbers and sizes used to describe bicycle tires are often very inaccurate. So all you have to do is just subtract 28 from 21 and divide your answer by two!! 28-21=7 7/2=3.5
Circumference = (pi) x (diameter) = 41 pi = 128.805 inches (rounded)
circumference = 2*pi*radius or diameter*pi
Circumference = 2*pi*radius or diameter*pi
20 X 3.14=62.83
