Question

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

Answer 1

#BAL

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

Answer 2

Answer: #BAL

Step-by-step explanation: ji

Radius 35 cm or 0.35m.

Circumference of circle

=2pi r =2×22/7×0.35

=22m

No. Of revolutions =1650/35m

= 50 revolutions
