Question

The diameter of a cycle wheel is 14 cm how many revolution will make in 5.5 km

Answer 1

Step-by-step explanation:

diameter of wheel=14cm

radius=07cm

so circumfarance of wheel = 2πr

= 2(22/7)(7)

=2×22

=44cm

so in 1 revolution cycle wheel covers 44 cm

now 5.5km=5500m=550000cm

so 44cm covered in = 1 revolution

550000cm covered in = ? (how much)

revolution covered in 5.5km=550000/44

=12500cm

so 12500cm= 125m=0.125km is covered distance
