Question

The wheel of a carriage makes 1000 revolutions to cover a distance of 4400m Find the diameter of the wheel​

Answer 1

The Wheel makes 1000 revolutions to cover 4400 m,

then the circumference of wheel will be,

$\frac{4400}{1000} m = 4.4m$

Circumference of circle = $2 \pi \:r$

$=> 4.4 = 2 \times \frac{22}{7} \times r \\ => 4.4 = 6.28 \times r \\ => r = \frac {4.4}{6.28} \\ => r = 0.70 m \\ d = 2r \\ d = 2 \times 0.70 = 1.4m$
