Calculate the length of an arc of a circle, radius 21m, whichsubtends an angle of 600 at the centre of the circle. (take tt=22/7)(a) 0.22m (b) lim (c) 22m (d) 2.31m (e) 23.1m

I'm guessing the angle is supposed to have measure 60º, not 600º... In this case,

That is, the length of the arc we care about occurs with the circle's circumference in the same ratio as the measure of the central angle it subtends occurs with one complete revolution of the circle. Then with , we have

so the answer is C.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
