Determine the lenght of arc and the area of the sector subtended by an angle of 60° in circle of radius 3 m(adsbygoogle = window.adsbygoogle || []).push({});

Ok First change 60to radian measure. 60 x pi / 180° = 2pi / 6

Then.. I used the formula s = rθ 3(2pi/6) = 6pi/6 = pi <--- Is this right??

And how can I find the area which formula can I use?
