Find the length of the arc if the angle at the centre of the circle of radius 7 units is 60o
Answer & explanation
Correct answer: option 3
Formula Used
Length of arc = \(\frac{\theta }{360}\) x 2\(\pi \)r
Solution
Length of arc = \(\frac{60}{360}\) x 2 x \(\frac{22}{7}\) x 7 = \(\frac{22}{3}\)
Therefore, the length of the arc is \(\frac{22}{3}\) units.
