Question

a bicycle wheel makes 5000 revolutions in moving 11 km find the circumference and the diameter of the wheel in short method

Answer 1

$\boxed{hey.....}$
$\underline{given}$
>Distance covered by a wheel in 5000 rounds = 11 km
= 1100 m
$> > distance \: of \: 1 \: round \: = \frac{11000}{5000}$
$= > \frac{11}{5}$
$distance \: of \: 1 \: round \: = circumference = \pi \times d$
$diameter = \frac{11}{5} \times \frac{7}{22}$
$diameter = \frac{7}{10}$
$diameter = 0.7 \: or \underline{\: 70cm}$
so, HERE IS YOUR ANSWER
