GCSE/IGCSE MATHS: Sector of a circle
Can you solve this multi-step Arc Length and Sector question without dropping marks? 🇬🇧🇸🇦🇶🇦🇦🇪👇
Arc length, perimeter of a sector, and circle theorems are regular 4- to 6-mark questions on Edexcel, Cambridge (CIE), AQA, and OxfordAQA Higher Tier papers. Even top students often lose easy marks on these big questions by forgetting to add the two straight radii to find the total perimeter, or mixing up the angle fraction \frac{\theta}{360}.
Whether you are a student targeting a Grade 8/9 in your upcoming term mocks, or a parent supporting your child ahead of the 2027 exams across the UK, UAE, Qatar, or Saudi Arabia, mastering how to unpack these multi-step geometry problems early in the academic year is essential.
In this video, I walk through a challenging past paper question step-by-step to show the exact working examiners look for.
