The number of revolutions completed by rotating a wheel in a given distance
= Distance covered/Circumference of Wheel
**Circumference of given Wheel
= 2πr
= 2×3.14×21 (since, r = 21cm)
= 131.88 cm
**Distance covered (cm) = 924×100 = 92400 cm
Substituting the generated values, we get;
Revolutions = 92400/131.88
= 700.63694268
Approx. 701 Revolutions will be completed by the wheel.
