2πr
r=70cm
2×22/7×70=440cm
distance=circumference×revolutions
that means =440cm×1000=440000cm
440000cm=4400m=4.4km
r=70cm
2×22/7×70=440cm
distance=circumference×revolutions
that means =440cm×1000=440000cm
440000cm=4400m=4.4km

Answer:
Step-by-step explanation:
Diameter=70cm
Perimeter of a circle=2 pi r square
radius=35
2*22/7*35=220cm
distance=circumference*revolutions
=220*1000=220000cm
=2200m
Hope helps
