Question

The radius of the circular wheel is 1.4m. How many revolutions will it make in travelling 88km? (Take π = 22/7 )

Answer 1

10000 revolutions

Radius of circular wheel, r = 1.4m

Circumference of circle, C=2πr

$C=2πr = 2 \times \frac{22}{7} \times 1.4 = 44 \times 0.2 = 8.8m$

In one revolution wheel will travel 8.8m = 0.0088km or 88/10000

Revolutions taken to travel 88km = 88/(88/100001 = 10000

Answer 2

Answer:

10000

Step-by-step explanation:

The radius of the circular wheel is 1.4m.total revolutions will it make in travelling 88km is =(10000)
