Question

The radius of a wheel of a bus is 0.70m how many revolution will it complete in covering 22 km

Answer 1

Answer:

circumference of the wheel = 2πr=2π*0.7m

number of revolutions=distance/circumference

                                    =22*1000/(2π*0.7)

                                    =5000 revolutions

Step-by-step explanation:

Answer 2

Answer:

Radius(r)= 0.7

Circumference= 2*22/7*0. 7=4.39...=4.4 (approx.)

No. Of Revolutions = 22000÷4.4

= 5000

Step-by-step explanation:

22km= 22000m

No. Of Revolutions= (Given Distance) ÷ (Circumference)
