Given that
1000 revolutions make 0.88 km
1 revolution make
=0.88km/1000
=880m/1000
=0.88m
Perimeter of the wheel = 0.88m
2 π r = 88cm
r = 88 x 7/2 x 22
r = 14cm
1000 revolutions make 0.88 km
1 revolution make
=0.88km/1000
=880m/1000
=0.88m
Perimeter of the wheel = 0.88m
2 π r = 88cm
r = 88 x 7/2 x 22
r = 14cm
