Answer:
Radius = 28cm
Circumference = 2πr = 2 × 22/7 × 28 cm = 176cm
Hence, in one revolution, the bicycle wheel travels 176cm.
704m = 704 × 100 cm = 70400cm
Therefore, number of turns = 70400÷176 = 400

Answer:
The distance traveled in one revolution is equal to the perimeter of the wheel. P = 2πr = 2*(22/7)*28 = 176cm.
