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).
Circumference is equal to the diameter multiplied by pi, or 3,14. Multiply 65 x 3.14.
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.
Area of bicycle wheel: pi*13 squared = 169*pi or about 531 square inches

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 circumference of the wheel can be calculated using the formula C = π*d, where d is the diameter of the wheel. Substituting the values given (d = 700 mm), the circumference is approximately 2199.11 mm. Since there are 1000 mm in a meter, the distance traveled is 2,000 meters. Therefore, the number of revolutions can be found by dividing the distance traveled by the circumference of the wheel. This results in approximately 0.91 revolutions.
Find how far one revolution goes - this is the circumference of the wheel; from this the radius can be calculated: 1000 revolutions = 628m 1 revolution = 0.628m =62.8cm Circumference = 2{pi}radius (pi ~= 3.14) radius = circumference / 2{pi} ~= 62.8cm / (2 x 3.14) = 62.8cm / 6.28 = 10cm
Radius of the wheel: 24/2 = 12 inches

11" Diameter x 3.145159 = 34.5575" Circumference 34.5575" Circum x 150 Revs = 5,183.6278" or 431.9689'
We had this question just the other day as well. 28-21, you do the math.
