Example Question #11 :Circles
What is the equation for a circle centered atpassing through the point
The equation of a circle is defined bywhere the center isand the radius is r. The radius is the distance from the center to any point on the circle, so we can use the distance formula to calculate it:
The equation is thenor more simplified,
Example Question #12 :Circles
Write the equation for a circle with centerand passing through the point
To determine the radius of the circle, use the distance formula:
The equation for the circle isor more simply
