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
r = 14
c = 2πr
= 2 x 22/ 7 x 14
=88 cm
distance covered in 100 revolution = 88 x 100 = 8800 m

ok, so we have the diameter which is 28 cms
So the radius of the wheel is 28/2=14cms
so, r=14cm.
now the distance it covers in 1 revolution is 2πr
2πr=2*(3.14)*14
=88 cms.
so it covers the distance of 88 cms in 1 revolution. ^_^
Now, in 100 revolution it goes on the distance of....
=88*100
=8800 cms.
hope it helped. ^_^
