An arc of a circle subtends an angle of 60o at the centre. If the radius of the circle is 3cm, find , in terms of \(\pi\), the length of the arc
-
\(\pi\)cm
- 2\(\pi\)cm
- 3\(\pi\)cm
- 6\(\pi\)cm
The correct answer is: A
Explanation
Length of arc = \(\frac{\theta}{360} \times 2\pi r\)= \(\frac{60}{360} \times 2\pi \times 3cm\)
= \(\pi\)cm
