Answer:
Explanation:
Given radius r = 42 cm
Distance = 66km
No of revolutions = distance/circumference of a wheel
= (66 × 1000 × 100)/2πr
= 6600000/2×22/7
= 1000×100/4
= 100000/4
= 25000 revolutions

Answer:
Heya mate.....
Given,
Radius = 42cm
Distance = 66km = 66000cm
Circumference = 2 × pie × r
= 2 × 22/7 × 42
= 264cm
No. of revolutions = 66000/264
= 250
Hence, the wheel will take 250 revolutions to cover 66 km.
Hope it helps.....
