🚨 CCEA GCSE Maths Challenge! 🚨
Think finding the radius of a cone in a NON-calculator exam is impossible? 🤔 In this M7/M8 past paper question, we're given the volume of a cone and told to use π = 22/7, meaning no calculator allowed! 📚✏️
In this walkthrough, I'll show you how to rearrange the volume formula, simplify fractions, use algebra efficiently, and find the radius step-by-step. This is a great question for practising volume, cones, radius, algebraic manipulation, substitution, square roots, and non-calculator techniques that often appear in CCEA exams.
Stay until the end to see the quickest method and avoid the most common exam mistakes! 🔥
