Question

Diameter of the wheel of horse-cart is $1.40$ metre. How much distance(in metres) is covered (correct upto one decimal place) by this wheel in one rotation?

Answer 1

Diameter of wheel of horse cart $\left(d\right)=1.40m$

$\Rightarrow$ Radius of wheel of horse cart $\left(r\right)=\frac{d}{2}=\frac{1.40}{2}=0.7m$

$\therefore$ Distance covered in one rotation $=2\pi r=2\times \frac{22}{7}\times 0.7=4.4m$
