### Solution:

We have a piece of wire of length 22cm that is bent in the form of an arc of a circle that subtends an angle of 60∘60∘ at its centre point. With this information, we need to find the radius of the circle made by the arc.
We also have given . Now we can use it to find the value of the radius
we get the radius of the circle is So, Option 1 is correct.
