Question:The diameter of a wheel is 1.26 m. How far will it travel in 500 revolutions ? 

A 2530 m 
B 1980 m 
C 1492 m 
D 2880 m 

+ Answer
B 

+ Explanation
Radius of the wheel = 0.63 m.

Distance moved in 1 revolution = circumference

 `= (2 xx 22/7 xx 0.63) m`

`= 3.96 m.`

Distance moved in 500 revolutions 

`= (500 xx 3.96) m`

`= 1980 m`
