Question

a bicycle wheel has a diameter of 770 cm how many times should the wheel rotate to cover a distance of 4.4 kilometre​

Answer 1

h = 7.7m

r = 3.85m

distance covered = 4400m

revolution = distance covered ÷ CSA

$\frac{4400}{2 \times \frac{22}{7} \times 3.85 \times 7.7 } \\ 23.61(approx)$
