Answer:
Diameter=28cm
Therefore radius=28/2=14cm
In 1 revolution it will cover
2*π*r
2*22*14/7=88cm
Therefore in 140 revolutions it will cover (88*140)cm=12,320cm

Step-by-step explanation:
diameter of bicycle wheel = 28 cm
radius of wheel = 28/2
= 14 cm
circumference of bicycle wheel = 2π r
= 2*22*14
= 2*22*2
= 88 cm
88/100 m = 22/25
=
22/25*140
=12320 cm
