Question

the diameter of the wheel of a car is 70cm. How many revolution will it make to travel 1.65 km​

Answer 1

we have to find circumference of the circle because in this it talks about diameter and then we will the event and we will find about the how many Revolution it takes to use multiple the circumference multiply the distance

Answer 2

ANSWER:

750 REVOLUTIONS

Step-by-step explanation:

Given it should travel 1.65 km = 1.65 ×1000×100 cm

             = 165000 cm

now,radius = diameter/2

          = 70/2

          =35 cm

now, circumference = 2π r

                                = 2×(22/7)×35

                                = 220 cm

it means, 220 cm = 1 revolution

      then, 165000 cm = 165000/220

                                  = 750 revolution
