1st find the diameter of the wheel
diameter = pi×d(diameter)
=22/7 × 77
=22 × 11 = 242 cm
diameter = 242 cm
500 revolution =500×242
=121000 cm
121000 cm = 1210 m
1210 m = 1.21 km

Answer:
Radius = 77/2
Circumference =2πr
= 2*(22/7)*(77/2)
= 22*11 = 242 cm
Distance covered by the wheel for 500 revolution
= 500*242 =121000cm = 1210m = 1.21 km
