5 resourcesCircle Geometry (AQA Level 2 Further Maths)
The equation of a circle for AQA Level 2 Further Maths, with GCSE-friendly numbers: centre, radius and equation; completing the square; the equation from a diameter or a centre and a point; points inside, on or outside and the…
⚙️ WorksheetEquation of a Circle: Fill in the Blanks
A table of circles: each row gives the expanded equation, the (x − a)² + (y − b)² = r² form, or the centre and radius; fill in the rest. Surd radii, rearranged equations and non-circles on higher levels.
🧮 ToolCircle Explorer
Drag a circle’s centre and radius on a large coordinate grid and see its equation in both forms, with the working for completing the square (or type an equation in either form). Points inside, on or outside, shortest and longest…
