0.42 * 13.2=5.544
Diameter = 40 cm implies circumference = 40*pi = 125.7 cm So, in travelling 352 metres = 35200 cm, the wheel will rotate 35200/125.7 = 280.1 times (approx).
A wheel 2 feet in diameter turning 10000 revolutions per hour is going, at the rim, 17.45 feet per second, or 25.6 miles per hour.
Circumference is equal to the diameter multiplied by pi, or 3,14. Multiply 65 x 3.14.
Area of bicycle wheel: pi*13 squared = 169*pi or about 531 square inches

The recommended tire size for a bicycle with a wheel diameter of 28mm is typically 700c.
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 !
The recommended tire size for a bicycle with a wheel diameter of 29x2.25 inches is typically 29 inches in diameter and 2.25 inches in width.
The recommended tire size for a bicycle with a wheel diameter of 40 622 is typically 700c x 40mm.
The standard size of bicycle wheel bearings is typically 1/4 inch in diameter.
If the diameter is 700 mm then the radius is 700/2 = 350mm The circumference of the circle is 2πr = 2π.350 = 2199.115 mm 1 kilometre = 1000 metres = 1000000 mm : 2km = 2000000mm Number of revolutions = distance travelled ÷ circumference of wheel. 2000000 ÷ 2199.115 = 909. 46 revolutions
Radius of the wheel: 24/2 = 12 inches
