Something in Common 6: Annulus Volume of Revolution

(0)
Earliest recommended Year group: Year 13. Pupils are given different segments of circles and asked to calculate their volumes of revolution. They all have the same volume. This is from the “Something in Common” collection of resources by John Burke. They allow consolidation of key skills, prevent students from copying each other (as all the questions are different), make marking and assessing easy for the teacher (as all the answers are the same!), and provide a lovely extra challenge for students as they try to figure out exactly what is going on! To access the full collection, and read John’s background notes, please visit: http://www.mrbartonmaths.com/common.htm
