  3. Estimating wheel rotations involves calculating the wheel’s circumference and dividing the distance by it. First, measure the wheel’s diameter and multiply it by π (3.14) to get the circumference. Use the formula: rotations = distance ÷ circumference. For example, if the wheel circumference is 2 metRead more

    Estimating wheel rotations involves calculating the wheel’s circumference and dividing the distance by it. First, measure the wheel’s diameter and multiply it by π (3.14) to get the circumference. Use the formula: rotations = distance ÷ circumference. For example, if the wheel circumference is 2 meters and the distance is 10 meters, the wheel will rotate 5 times. Observing the wheel while riding can also confirm the estimation.
