Question

a diameter of a bicycle wheel is 28 CM what distance will it cover in 100 revolutions

Answer 1

D = 28 cm ,

r = 14

c = 2πr

= 2 x 22/ 7 x 14

=88 cm

distance covered in 100 revolution = 88 x 100 = 8800 m

Answer 2

dia=28cm

radii=14cm

circumference =2×Pi×r

=2×22/7×14

=88cm it will cover in one revolution

therefore for 100 revolutions

= 88×100

=8800cm

that is 88 metres.
