Answer 2

Answer:

750

Step-by-step explanation:

=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
