Question

Step by step clearly ​

Answer 1

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
