Question

If a wheel of radius r equal to 2 m, turns through ar
angle of 30', then the distance through which any
point on its rim moves in SI units is
​

Answer 1

Answer:

A wheel of radius r moves through and angle of 30o.

If the wheel moves a full circle, it moves through an angle of 360o.

In such a situation, the distance moved by a point on its rim is equal to the circumference of a circle with radius r=2πr.

⇒ If a wheel of radius r moves through an angle of 30o, the distance moved by a point on its rim is
