Question

The dimeter of a wheel of a cart is 1.05m find distance if it takes 1000 rotations

Answer 1

Diameter=1.05m
Radius=1.05/2=0.525m
Circumference=2πr
=2×22/7×0.525
=3.3m
Distance=1000×3.3=3300m

Answer 2

We have,

Diameter of wheel of a cart = 1.05 m.

thus, radius = $\frac{1.05}{2} = 0.525$

Now, in rotation distance travelled by wheel = $2\pi \: r$

thus,putting, r = 0.525.
Distance travelled in 1 rotation =$2 \times 3.14 \times 0.525 = 3.297$

Thus,in 1000 rotation Distance travelled is ,

$3.297 \times 1000 = 3297\: m$
