circumference of wheel = total distance × no. of rotation
=1000×1.76
=1760 km
So
2×pie×r=1760
2×22/7×r=1760
r=1760×7/22×2
r=280
=1000×1.76
=1760 km
So
2×pie×r=1760
2×22/7×r=1760
r=1760×7/22×2
r=280

The wheel of a car travelling a distance =17.6 km
the wheel of a car rotated 1000 times in travelling a distance = 17.6×1000= 17600 km
circumference = 2×pie×r
17600 = 2×22/7×r
r= 17600 ×7/2×22
radius = 2800km
