diameter of the wheel = 77
radius of the wheel = 77/2 = 38.5
now,
area of the wheel = πr^2
= 22/7*38.5*38.5= 4658.5m
total area covered by the car = 4658.5 *500= 2329250km
radius of the wheel = 77/2 = 38.5
now,
area of the wheel = πr^2
= 22/7*38.5*38.5= 4658.5m
total area covered by the car = 4658.5 *500= 2329250km
Exact:
u must take perimeter not Area
@exact i am soo sorry, i did a very silly mistake i hope i could fix that in some way but anyways thank you soo much for bieng genrous enough to infrom me about the same!
no problem dude !

solution:
distance covered in 1 revolution = circumference of the circle
circumference of circle=2πr
radius = diameter/2
=77/2
2πr
=2×22/7×77/2
=242 = distance covered in 1 revolution
•in 1 revolution 242 distance is covered
•in 500 revolution distance covered =500×242
=121000 km
