Question on: WAEC Mathematics - 2009
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
A
\(\pi\)cm
B
2\(\pi\)cm
C
3\(\pi\)cm
D
6\(\pi\)cm
Ask EduPadi AI for a detailed answer
Correct Option: A
Length of arc = \(\frac{\theta}{360} \times 2\pi r\)
= \(\frac{60}{360} \times 2\pi \times 3cm\)
= \(\pi\)cm
= \(\frac{60}{360} \times 2\pi \times 3cm\)
= \(\pi\)cm
