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.

Q: If a wheel is 2 feet in diameter and does 10000 revolutions per hour how fast is it going?

To figure out how long a revolution is you need to find the circumference of the wheel. If the diameter is 70 centimeters, then to get the circumference you multiply the diameter by pi (3.14). That equals 219.8. centimeters. Then you convert 66 meters into centimeters, and that is 6600. Then you divide 6600 by 219.8 and get 30 revolutions.

0.42 * 13.2=5.544

Diameter = 68 cm => circumference = pi*d = 213.63 cm = 2.1363 m To travel 100 m the wheel makes 100/2.1363 = 46.81 revs.

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).

The revolutions per minute of a bike wheel depends on the size of the wheel, the speed you are riding, and other factors. It is generally thought it can spin at 2 revolutions per second.

To find the radius of the wheel, we first calculate the circumference of the wheel using the formula: Circumference = 2 * π * radius. Since the wheel travels a distance of 11 km in 5000 revolutions, each revolution covers a distance of 11 km / 5000 = 0.0022 km. The circumference of the wheel is twice the distance covered in one revolution. Thus, we have Circumference = 2 * 0.0022 km = 0.0044 km. By setting up the equation 0.0044 km = 2 * π * radius, we can solve for the radius as 0.0044 km / (2 * π) ≈ 0.0007 km, or 0.7 meters.

The circumference of an 8-inch diameter wheel = d*pi = 8*pi. Each revolution will advance the wheel by one circumference, so 2000 revolutions per minute would be 2000 * 8 * pi = 1600pi feet per minute.

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

0.42 * 13.2=5.544

It will travel: 50*12*pi = 1885 inches rounded to the nearest integer

40 / 5 = 8 8 * 2 = 16 Wheel B turns 16 times.

Since it'll be rolling around the outside of the circle, the distance traveled will be in some multiple of the circumference. So, dividing the distance by the circumference will give the answer. C = πD = 6π revolutions = distance / circumference = 108π / 6π = 18 revolutions
