$140$

Vedclass · Answer

(A) The diameter of the wheel is $d = 40 \, cm$.The circumference of the wheel is given by $C = \pi d = \frac{22}{7} 	imes 40 = \frac{880}{7} \, cm$.The total distance to be covered is $176 \, m$. Converting this to centimeters,we get $176 	imes 100 = 17600 \, cm$.The number of revolutions is calculated by dividing the total distance by the circumference:$	ext{Number of revolutions} = \frac{	ext{Total distance}}{	ext{Circumference}} = \frac{17600}{\frac{880}{7}} = \frac{17600 	imes 7}{880} = 20 	imes 7 = 140$.

The number of revolutions a wheel of diameter $40 \, cm$ makes in travelling a distance of $176 \, m$ is:
