The Circumference of a wheel 1.1m dia is 1.1*pi
Thus 2000/(1.1*pi) is the number of turns the wheel will make.
2000/3.456 = 578.7 revolutions to one decimal place
(pi assumed to be 3.14159)
31 turns
36 pi
18.4 inches
If the rim doesn't slip on the ground, then the distance for each revolution is (diameter x pi).2.5 x pi = 7.854 (rounded)

because the wheel turns through a much greater distance than the axle.but the smaller turn of the axle is more powerful.witten by-brenda v.=========================Answer #2:-- The fact that the wheel turns through a greater distance that the axle doesis a result, not a cause, of the wheel being bigger than the axle.-- The axle is not more powerful than the wheel. Ignoring losses, they must bothhave the same power. The axle's force is greater than the wheel's force, but to payfor it, the axle must turn through greater distance. Same as all the lever stuff.-- The diameter of the wheel needs to be greater than the diameter of the axleonly if you'd prefer not to have the axle scrape on the ground.

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
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
They measured the distance the wheel traveled on the ground which would be the same as the circumference of the wheel. If they then measured the diameter of the wheel and divided the circumference by the diameter they would have a value for pi.
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 !
36 pi
5280 feet/1320 turn = 4 foot circumference 4 foot cirumference/ (pi) = 1.273foot diameter
Linear distance of one revolution = 3.14 x diameter = 3.14 x 20 = 62.8 meters
A larger diameter wheel rotates a fewer number of times to cover the same distance as a smaller wheel.
If its circumference is 21.98 feet then its diameter is 21.98/pi = 7 feet rounded up.
