Can You Solve This Without a Calculator? | GCSE Maths Geometry & Mensuration (Edexcel 9–1)

Test your Geometry & Mensuration skills with this challenging no-calculator question from Pearson Edexcel GCSE Maths 9–1 Higher Tier Paper 1H (May 2020). In this video, we carefully solve a 5-mark exam-style problem where: 🔹 What’s covered: • Area of sectors of circles • Subtracting areas to form composite shapes • Using algebra within geometry • Equating areas to form an equation • Solving for x without a calculator 🔹 Question overview: Shape A is formed by removing a smaller sector from a larger sector. Shape B is a circle with an algebraic diameter. Both shaded areas are equal — and you must show all working, just like in the real exam. ----------------------------------------------------------------------------------------------------------- Question : The diagram shows two shaded shapes, A and B. Shape A is formed by removing a sector of a circle with radius (3x – 1) cm from a sector of the circle with radius (5x – 1) cm. Shape B is a circle of diameter (2 – 2x) cm. The area of shape A is equal to the area of shape B. Find the value of x. You must show all your working.
