Answer 1

Step-by-step explanation:

Total distance=4.4km=4400m

Diameter=70cm=0.7m

Radius=0.7/2m

Circumference of wheel =2*π*r

=2*22*0.7/7.2

=22*0.1

=2.2m

Therefore, No. of revolution=distance/circumference

=4400/22

=2000

Answer 2

Answer:

Step-by-step explanation:

Total distance=4.4km=4400m

Diameter=70cm=0.7m

Radius=0.7/2m

Circumference of wheel =2*π*r

=2*22*0.7/7.2

=22*0.1

=2.2m

Therefore, No. of revolution=distance/circumference

=4400/22

=2000
