Vedclass · Answer

(A) The distance covered by a wheel in one revolution is equal to its circumference,which is $\pi D$,where $D$ is the diameter.For $n$ revolutions,the total distance $S$ is given by $S = n 	imes \pi 	imes D$.Given: $n = 2000$,$S = 9.5\, km = 9500\, m$.Substituting the values into the formula:$9500 = 2000 	imes \pi 	imes D$$D = \frac{9500}{2000 	imes \pi}$Using $\pi \approx 3.14159$:$D = \frac{9.5}{2 	imes 3.14159} \approx 1.51\, m$.Rounding to the nearest provided option,the diameter is $1.5\, m$.
