. The diameter of a wheel is1.26 m


How far will it travel in 500  revolutions ?

A: 1980 m

B: 2000 m

C: 2420 m

D: 1890 m

 

Best Answer

Explanation:

Given the diameter of the wheel is 1.26m.

(r)=diameter/2=1.26/2=0.63

Radius

Now, the distance moved in one revolution will be equal to the circumference of the circle.

So, 

1 revolution=2πr

500 revolution =500×2πr

=500×2×22/7×0.63

=13860/7=1980

So, the distance moved in 500 revolution is 1980m.

Final Answer:

The distance moved in 500 revolution is 1980m.
