You can put this solution on YOUR website!
The length of the whole circumference is 2pi%2Ar=12pi
The arc corresponding to 60%5Eo is 1%2F6 of that, so it measures
12pi%2F6cm = 2picm = about 6.28 cm
Your teacher may have expected you to convert
60%5Eo to pi%2F3 radians,
and then multiply that times the radius to get
%28pi%2F3%296cm = 2picm
