To calculate the number of revolutions a bike wheel makes, first determine the wheel's circumference using the formula ( C = \pi \times d ), where ( d ) is the diameter of the wheel. Next, measure the distance traveled by the bike. Finally, divide the distance by the circumference: ( \text{Revolutions} = \frac{\text{Distance}}{C} ). This will give you the total number of revolutions made by the wheel.
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 distance a wheel travels in three revolutions, first calculate the circumference of the wheel using the formula (C = 2\pi r). For a radius of 9 cm, the circumference is (C = 2\pi \times 9 \approx 56.55) cm. In three revolutions, the wheel would travel (3 \times 56.55 \approx 169.65) cm. Thus, the wheel travels approximately 169.65 cm in three revolutions.
In each revolution, the wheel would advance 2 x pi x radius. Multiply this by the number of revolutions.
