Question

The radius of wheel of a bus is 56 cm. find the distance (in metre)
covered by the wheel in 400 rotations.​

Answer 1

radius = r = 56cm

one rotation = circumference of circle

= 2 π r

= 2 × 3.14 × 56 = 351.68cm

• Distance covered = 400 rotation × circumference

= 400 × 351.68 = 140672 cm

• In meter, 140672/100 = 1406.72m

" 1406.72 m of distance the bus has covered "
