Question

The diameter of a car's tyre is 70cm.Find the distance covered by it in 5 rounds(use pi=22)
7

Answer 1

Dear Student,

Given that,
Diameter of Tyre =d=70cm,
Radius of Tyre=r=$\frac{d}{2}=\frac{70}{2}=35cm$
Perimeter of Tyre=2πr
$=2*\frac{22}{7}*35$
=2*22*5
=220cm

As we know,
Distance cover by 1 round of Tyre=Perimeter of Tyre=220cm
So, Distance cover in 5 round=5* Perimeter of Tyre
=5*220
=1100cm
