Question

a diameter of a wheel is 80 cm. How many revolutions will it make to cover 1256 metres (take 3.14)

Answer 1

Answer:

500 revolution

Step-by-step explanation:

$perimeter \: of \: \: wheel \: = \pi \times d \\ = 3.14 \times 80 \: cm \\ \: = 215.2 \: cm \\ = 2.152 \: m \\ number \: of \: revoltion \: = \frac{length \: to \: be \: covered}{length \: covered \: in \: 1 \: revolution} \\ = \frac{1256}{2.152} = 500$
