diameterd =1.40m
let the distance covered by the wheel =D
circumference of the wheel =pi1.40
distance D=circumference x number of rotation
D=1.40pix500
D=3.14x1.40x500
D=2198m
hence the cost of fencing at the rate of 50 per metre
=2198x50
=Rs.109,900

D=1.4m so r=0.7m
Now circumference =2pie*r =2*22/7*0.7=4.4m
So 1 rotation =4.4m>>500 rotations =500*4.4=2200m
Now it covers 77km=77000m so
Number of rotations =77000/4.4=17500
I think it is right answer If you like please mark as brainliest
