How to calculate the Circumference and Area of Circles
Two frequently returning formula's in all sorts of questions on IGCSE GCSE Maths exam are those of how to find the area or the circumference of a circle. Make sure to understand the language used and to be able to use it appropriately. Study all the tutorial videos during your maths revision to enable yourself to confidently work with these important formulas. I will explain to you step by step how to calculate the circumference and area of circles and guide you through many example maths questions. I have also included an investigation which will show us what is meant with pi and what its value roughly is (second video). Good luck and have fun!!
