Question

The wheel of a car rotated 1000 times in travelling a distance of 1.76 km. Find the radius of the wheel

Answer 1

1000 rotations cover 1.76 km

So, 1 revolution covers 1760/1000 m = 1.76 m  

So, circumference = 1.76 m

Radius = Circumference/2π = 1.76/2(22/7) = 1.76*7/44 = 0.28m

Answer 2

Answer:

0.28m hope it help you☺........
