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.
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.
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.
50*pi*500 = 78539.81634centimeters or 785 meters, correct to three significant figures.
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).

It will travel: 50*12*pi = 1885 inches rounded to the nearest integer
the diameter is 87 meters
Circumference of a circle: 2*pi*radius or pi*diameter (pi=3.14159...) Traveled distance = number of revolutions * circumference of tire To increase the distance you can either increase the number of revolutions or the circumference of the tire. Ex: Tire diameter = 1 meter => circumference = 3.14159 * 1 = 3.14159 meters So if you drive from home to Wendy's and the wheel spins 1000 times totally it means that you've traveled a distance of: 3.14159 * 1000 = 3141.59 meters
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.
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
200
In each revolution, the wheel would advance 2 x pi x radius. Multiply this by the number of revolutions.

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.
50*pi*500 = 78539.81634centimeters or 785 meters, correct to three significant figures.
