The sector aob of a circle is shown. the length of its arc ab is 8pi cm. the sector is folded so that the straight edges meet and form a cone. calculate the radius of the base of the cone.

If you're having trouble visualising this, I would suggest sketching the sector, cutting in out and rolling into the cone shape. Then you should see the relationship between the arc length of the sector and the circumference of the base of the cone.
