Question

A wire of 20 cm is bent to form an arc and subtend 60 angleatcentre

Answer 1

Answer:

We are given that a piece of wire 20 cm long is bent into the form of an arc of a circle subtending an angle of 60 degrees at its centre. So, here the arc length will be the same as 20 cm, as shown in the figure below. So we get the required radius of the circle as \[r=\dfrac{60}{\pi }cm\].
