A while ago I uploaded a set of resources on calculating the areas of shapes on flags, see here:
A number of people messaged me asking if I had one for circles - and here is is now! I had to get creative with finding flags I could use, and I’d recommend that you have already had a lesson on Area and Circumference before this, as the questions get very challenging! Thank you to @1hannahjones for making a number of corrections and clarifications!
