⛤HERE IS YOUR ANSWER⛤
Diameter of the wheel (d) = 70 cm
Radius of the wheel (r) = d/2 cm = 35 cm
The wheel is a circle, so perimeter (p) of the wheel is 2πr cm.
So, p = 2 × π × 35 cm
= 70 π cm
Total distance (d') = 1.65 km
= 1650 m = 165000 cm.
Therefore, total revolutions to be made by the wheel is
= d'/p
= 165000/70π
= 750 (approximately).
