Question

The wheel of the scooter covered $88$ m distance in $1000$ revolution. Find the radius of the wheel.

Answer 1

Distance covered in $1000$ revolutions $=88km$
Distance covered in $1$ revolutions$=\frac{88\times 1000}{1000}m$
$=88m$
Now, we know that the distance traveled in one revolution = circumference of the wheel
Thus, $2\pi r=88$
$=>r=\frac{88\times 7}{2\times 22}$
$=>r=14$
Thus, the radius of the wheel$=14m$
