Question

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

• A. $1980m$
• B. $2000m$
• C. $2420m$
• D. $1890m$

Answer 1

The correct option is A $1980m$

Diameter of the wheel $=1.26m$
Radius of the wheel $r=\frac{1.26}{2}$m
$=0.63m$
The distance traveled in one revolution = perimeter of the wheel $=2\pi r$
$=2\frac{22}{7}\left(0.63\right)$
$=3.96m$
Thus, distance traveled in $500$ revolutions $=500\times 3.96$m
$=1980m$
