Question

The diameter of the wheel of a cart is $1.05m$. How much distance will cart cover in $1000$ rotations of the wheel?

Answer 1

$1$ rotation is equal to the circumference

Now, circumference of a circle = $2\pi r$ or $\pi d$.

Circumference $=\pi \times 1.05$

$=3.29867$ m

Now, as cart covered $1000$ rotations, the distance is $3.29867\times 1000=3298.67$ m

(approximately $=3299$ m)
