A bicycle wheel has a radius of 0.33 m. how many revolutions does the wheel make when the bicycle is ridden 1 km? round to the nearest whole number. solved

Respuesta :

Diameter = Radius x 2 = 0.33 x 2 = 0.66 m

One revolution = πD = π (0.66) m = 2.073m

Number of revolution made in  1 km :

1 km = 1000 m

1000 ÷ 2.073 = 482 turns (nearest whole number)

Answer: Number of revolution = 482
