Question

A bicycle wheel is 56cm in diameter . How many complete turns does it make in travelling 1km ? Use the value ^ for( 22/7)

Answer 1

100 cm = 1 m

d = diameter

d = 56 cm = 0.56 m

C = Circumference

C = d * pi

C = 0.56 * 22 / 7 = 12.32 / 7 = 1.76 m


1 km = 1000 m

1000 / 1.76 = 568.181818

Answer 2

100Cm = 1 m
56cm = 0.56 m
3520Cm = 35.2 M
35.2 ÷ O.56=62.9 turns
