Radius of wheel = 28 cm
Circumference = 2 * pi * r
= 2 * 22 * 28 / 7
= 44 * 4
= 176 cm
Total Distance to be travelled = 704 m
= 70400 cm
No. Of revolution = Total distance / Circumference of wheel
= 70400 / 176
= 400
No. Of revolution = 400
Circumference = 2 * pi * r
= 2 * 22 * 28 / 7
= 44 * 4
= 176 cm
Total Distance to be travelled = 704 m
= 70400 cm
No. Of revolution = Total distance / Circumference of wheel
= 70400 / 176
= 400
No. Of revolution = 400

hii!!
here's ur answer..
given the radius of wheel is 28cm
in metres=28/100
=0.28m
first we have to find the circumference of the wheel=2πr
=2×22/7×0.28
=12.32/7
=1.76m
therefore no. of revolutions to cover 704m
=704/1.76
=400
hence it will take 400 revolutions.
hope this helps..!
