Sectors Revision GCSE Maths
A sector is part of a circle. GCSE sector questions often involve a fraction of 360 degrees.
Key Idea
If the angle is 90 degrees, the sector is one quarter of the circle because 90 out of 360 is one quarter.
Exam tip: Start sector questions by writing the angle as a fraction of 360.
Common mistake: Students sometimes use the full circle formula and forget to multiply by the angle fraction.
