Question

the diameter of a wheel of cycle is 70 cm how many revolution will it take to cover 550 metre​

Answer 1

Answer:N=250(number of revolution)

Step-by-step explanation:dia =70 cm,and in 1 revolution it will cover circumference 2*22/7*radius,  radiud=70/2=35

so,let it will take N revolution to cover 550 metre

N*2*22/7*35=550*100,since 1 m=100 cm

N=550*100*7/2*22*35

N=250
