Question

the diameter of the wheel is 140cm how many times the wheel will revolve in order to cover a distance of440m​

Answer 1

$Given \:diameter \: of \: the \: wheel (d) = 140\:cm$

$Distance \: covered \: in \: one$

$revolution=Circumstance \: of \: the \: wheel$

$= \pi d$

$= \frac{22}{7} \times 140$

$= 22 \times 20$

$= 440 \:cm$

$= 4.4 \: m \: --(1)$

$Let \: number \: of \: revolutions \:made \:to$

$cover \: the \: distance \: 440 \:m = \frac{440}{4.4}$

$= 100$

Therefore.,

$\red{ Number \: of \: revolutions } \green { = 100}$
