# 4. A pipe of wire 22 cm long is bent into the form of an arc of a circle subtending an angle of 60° at its centre. Find the radius of the circle. [use π = 22/7]

To find the radius of the circle formed by bending a wire into an arc subtending an angle of 60∘, we can use the formula for the length of an arc of a circle:

To find the radius of the circle formed by bending a wire into an arc subtending an angle of 60, we can use the formula for the length of an arc of a circle:
$$&space;\text{Length&space;of&space;arc}&space;=&space;\frac{\theta}{360^\circ}&space;\times&space;2\pi&space;r&space;$&space;Given:&space;Length&space;of&space;wire&space;($$&space;l&space;$$)&space;=&space;22&space;cm&space;Angle&space;subtended&space;($$&space;\theta&space;$$)&space;=&space;$$&space;60^\circ&space;$$&space;We&space;can&space;substitute&space;these&space;values&space;into&space;the&space;formula:&space;$&space;22&space;=&space;\frac{60}{360}&space;\times&space;2\left(\frac{22}{7}\right)&space;r&space;$$

$Let's&space;solve&space;for&space;$$&space;r&space;$$:&space;$&space;22&space;=&space;\frac{1}{6}&space;\times&space;\frac{44}{7}&space;r&space;$&space;$&space;22&space;=&space;\frac{22}{7}&space;r&space;$&space;Now,&space;let's&space;solve&space;for&space;$$&space;r&space;$$:&space;$&space;r&space;=&space;\frac{22&space;\times&space;7}{22}&space;$&space;$&space;r&space;=&space;7&space;\,&space;\text{cm}&space;$&space;So,&space;the&space;radius&space;of&space;the&space;circle&space;is&space;$$&space;7&space;\,&space;\text{cm}&space;$$.$
