Graphs and Equations of Circles Book: Math 3 (Green Book) Section: 5.2

2
Standard Equation of a Circle What do you think we need to write an equation of a circle? Radius Center Point on a Circle

3
Lets See What We Know The point (6, 2) lies on a circle whose center is at the origin. Find the radius. What formula do we need to use in order to find the radius? DISTANCE FORMULA!!!!!!!

4
Lets See What We Know The point (-2, -2) lies on a circle whose center is at (4, -5). Find the radius.

5
Lets Make Some Observations Whats the Radius? Where is the center? Here is the equation, how is it related to the circle?

6
Lets Make Some Observations Whats the Radius? Where is the center? Here is the equation, how is it related to the circle?

7
So we have determined… Let the center of a circle be the point (h,k) and the radius be r From our observations we have determined that the standard equation of a circle is:
