Question

A car has a tyre of diameter 28 cm. ___ km is covered by the car if the tyre rotates 150 times.

$(Use\pi =\frac{22}{7})$

Answer 1

The circumference of tyre = Distance travelled in each rotation

$=2.\pi .r$

Distance covered in 1 rotation = 88 cm

Distance covered in 150 rotation

$=88\times 150=13200cm=0.132km$
