Equations of Circles WORKSHEET

This worksheet is designed to provide scaffolding for learners to aid recognizing and finding equations of circles. Section A asks learners to select which equations from a list are circles and state the radius. Section B gives images of circles centred at the origin and asks learners to write the equation of each circle. Section C asks for the equation for a circle through a given point, and section D asks learners to sketch circle from their equations. An extension question asks learners to estimate the solutions to simultaneous equations involve one of the circles from section D and a straight line.
