Question

a bicycle wheel has daimeter is 88cm than find who many revolution in moving 60 km by whhel​

Answer 1

Step-by-step explanation:

radius,r of wheel=88/2=44

so, circumference of wheel=2×π×r

=2×44×π=88π cm

now distance travelled by wheel=60km=60×100000 cm=6000000cm

so, revolution done by wheel in moving 60 km=6000000/88π

= 262500/121 =2169.42 revolutions. (approx.)
