That the formular for the circumference of a circle (pii D)
The answer should be 4.254
Rotations and distance tells you about the circumference and this tells you about the diameter. How about a specific problem?
wheel diameter times pi times number of rotations

Firstly I'm assuming that the wheel's diameter is 35cm. If it is not in cm, then you will need to fix the following calculations. a = v2/r Calculating the speed of the clay comes to approximately 1.65m/s Substituting into the formula gives an acceleration of approximately 7.8m/s2 (If you were actually looking for an angular acceleration, you will need to use a different formula)
Circumference of wheel in cm: 2900/23 Diameter of wheel: (2900/23)/pi = 40 cm rounded to the nearest integer
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
Rotations and distance tells you about the circumference and this tells you about the diameter. How about a specific problem?
Diameter = 3.2 ft. Circumference = 3.2 ft * pi = 10.05 ft. 1 min * 60 mph = 1 mile 1 mile = 5280 ft. # of revolutions = Distance traveled / Wheel Circumference
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
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.
I need help
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

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
Circumference is diameter times Pi, you do the math.

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.
