Summary
Circumference and perimeter of a sector
Measurement (Year 9)
Year 9
This video continues the Year 9 series on Using Units of Measurement looking at the Circumference and Perimeter of a sector. Building on the work covered in a previous video (and content from the previous years), I look at how to find the circumference of a whole circle, the arc length of a circle and how to use the information to then go on and find the perimeter of a sector. There are lots of worked examples all explained clearly with theory. There is even some humour thrown in at times too. I pride myself on the easy to understand way I present my videos and would love to hear your feedback!
