n × Circumference of wheel = 22 km
n × 2 π r = 22 km
n = 22 km / (2 π r)
= 22 × 10^3 m / (2 × 22/7 × 0.7 × 10^-2 m)
= 500,000
= 5 lakh
Wheel makes 5 lakh revolutions to cover 22 km
n × 2 π r = 22 km
n = 22 km / (2 π r)
= 22 × 10^3 m / (2 × 22/7 × 0.7 × 10^-2 m)
= 500,000
= 5 lakh
Wheel makes 5 lakh revolutions to cover 22 km
