Let the radius of wheel be r
then its perimeter will be 2πr
in 50 revolution it covers distance =222m
                                   50 x 2πr=222
                                              r=222/50 x 2 x π
                                              r=0.70 m
therefore diameter =2r=2 x 0.70
                           =1.4 m ans..
