Step-by-step solution

3 steps
  1. Calculate the circumference of the bicycle wheel.

    The diameter (dd) is 63 cm63 \text{ cm}. The circumference (CC) is given by the formula C=πdC = \pi d. We are given π=227\pi = \frac{22}{7}.

    C=227×63 cmC = \frac{22}{7} \times 63 \text{ cm} C=22×9 cmC = 22 \times 9 \text{ cm} C=198 cmC = 198 \text{ cm}
  2. Calculate the total distance traveled in 100 revolutions.

    The distance traveled in one revolution is the circumference.
    Total distance = Circumference ×\times Number of revolutions

    Total distance=198 cm×100\text{Total distance} = 198 \text{ cm} \times 100 Total distance=19800 cm\text{Total distance} = 19800 \text{ cm}
  3. Convert the total distance from centimeters to meters.

    Since 1 meter=100 centimeters1 \text{ meter} = 100 \text{ centimeters}, we divide the total distance in centimeters by 100.

    Total distance in meters=19800100 m\text{Total distance in meters} = \frac{19800}{100} \text{ m} Total distance in meters=198 m\text{Total distance in meters} = 198 \text{ m}

    The bicycle travels 198 meters for 100 revolutions.
