Answer» Answer: The wheel has to ROTATE 183636 times Step-by-step explanation: Diameter (including the tyre) = 70 cm Radius (including the tyre) R = (Diameter)/2 = 70/2 = 35 cm Perimeter of the wheel = $2\pi R$ = $2\frac{22}{7} 35$ cm = 220 cm So in one REVOLUTION of the wheel, the MOVES 220 cm. Now, 404 km = 404 * 1000 metre = 404 * 1000 * 100 cm = 40400000 cm The cycle moves 220 cm in 1 revolution of the wheel The cycle moves 1 cm in $\frac{1}{220}$ revolution of the wheel So, the cycle moves 40400000 cm in $\frac{1}{220}*40400000$ revolution of the wheel = 183636 revolution of the wheel.

Answer:

The wheel has to ROTATE 183636 times

Step-by-step explanation:

Diameter (including the tyre) = 70 cm

Radius (including the tyre) R = (Diameter)/2 = 70/2 = 35 cm

Perimeter of the wheel = $2\pi R$ = $2*\frac{22}{7} * 35$ cm = 220 cm
