Circle Equation for Grade 10 | JensenMath

In this lesson you will learn about the equation of a circle centred at the origin or any point (h,k). You will learn how to write the equation of a circle given the radius or a point on the circle. You will also learn how to determine if a point lies inside, outside, or on a circle. Finally, you will learn how to calculate the shortest distance from a point to a circle. This lesson corresponds to section 2.4 of the McGraw Hill Principles of Math 10 textbook. Go to jensenmath.ca for supporting materials.
