Answer 1

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.
