The small wheel has to turn more to travel the same distance as the larger wheel.
Circumference is diameter times Pi, you do the math.
Assuming what you're asking is for the circumference (distance around the entire wheel) the formula is r*2*pi. In this case the circumference is roughly 157 inches.
That completely depends on the size of the wheel ... the rear wheel on a farm tractor wouldn't turn as many times in 1 mile as the wheel on a skateboard would. If the tire on a car is 30 inches across, then it turns 672 revolutions (rounded number) in one mile.
A sneeze can travel 15 feet. Be sure to turn your back if someone has sent one in your direction.
A Ferris Wheel
The axle of a Ferris wheel is the part that the wheel spins around. It is in the center of the whole construction. So when you say Ferris wheel you don't say Ferris wheel and axle, you just say Ferris wheel. ... or the same "why" is when folks say" WOKEN UP (dangling particple...inncorrect use)... instead of the correct word..."Awaken" ... " I was "woken up" (Awakend) by the banging of trash can lids being thrown..."

There's a power plant which drives either a chain or driveshaft to make it turn. Some might even use a hydraulic system.
To turn the front wheel to determine the direction of travel.
For high speed you want a big chainwheel (by the pedals) and a small sprocket(by the rear wheel). But this is assuming the rider is strong enough to turn the cranks properly. If the rider can't turn the cranks at 80-100 turns/minute, he'd probably be faster with a smaller chainring/bigger sprocket.
If the rider pushes down on the forward side, the top run of the chain goes tight, the rear Wheel begins to turn and the bike starts to move forward.

go into the carnival. once you are there go down the main hallway and turn right. then turn right again. you will have a freak show in front of you and a ferris wheel to your left. go to the corner in between them and there it is
Geometry of wheels on a car. During a turn, the front wheels travel different distance. Ackermann concept corrects this. On a right turn the left wheel must travel further.
Don't turn the wheel.
