An arc of circle of radius 2cm subtends an angle of 60º at the centre. Find the area of the sector
A
\(\frac{2 \pi}{3}\)cm2
B
\(\frac{\pi}{2}\)cm2
C
\(\frac{\pi}{3}\)cm2
D
\(\pi\)cm2
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
Area of a sector \(\frac{\theta}{360}\) x \(\pi\)r\(^2\)
= \(\frac{60^o}{360^o}\) x \(\pi\)2\(^2\)
= \(\frac{2 \pi}{3}\)cm2
