the diagram shows a sector of a circle of radius 8 units, formed from an angle of size 300 degrees. find the exact length of the arc.

So 300 / 360 = 5/6. The arc thus is 1/6 of the circumference.

 

The circumference is 8^2 π = 64π. 1/6 of that is 64π/6 = 32π/3.

 

If you don't understand anything feel free to ask!
