Welcome to our GCSE circles revision quiz. As we embark on our journey to explore the fascinating world of circles and their properties, we've added an exciting twist to our revision session. Dive into our video short, looking at a different kind of circles - crisps! This engaging footage not only makes math revision more enjoyable but also provides a real-world context to our study.
Can you imagine a world without circles? There would be no wheel, no pulleys, no transport, no machinery. And there would be no reason to give the irrational number 3.14159… its special name. Circles are everywhere, and this GCSE Maths quiz will test your knowledge of the circle facts.
So what is a circle? In geometry terms it is defined as the set of points, or a path, such that every point on the path is the same distance away from another point, the centre of the circle. Imagine a post in the middle of a big field. A dog is tied to the post, on a lead that is 5 metres long. If the lead is always tight, what shape on the ground will the dog trace out as it runs around? The lead would be the radius of the circle, and the dog’s path is the circumference.
