Question

If a wheel of the radius r turns through the angle of 30, then what is the distance through which any point on its rim moves?

Answer 1

Answer:

Explanation:

The wheel moves a full circle, it moves through an angle of 360°.

So,

In that case, the distance moved by a point on its rim is equal to the circumference of a circle with radius.

Hence,  

⇒ r = 2πr

Now, In the case of,  If a wheel of radius r moves through an angle of  30°.

The distance moved by a point on its rim :

2πr*30/60

πr/6
