Math Problem Statement
What is the standard form of the equation of the circle whose center is at (h, k)?
Solution
The standard form of the equation of a circle with center at and radius is:
Where:
- represents the coordinates of the center of the circle.
- is the radius of the circle.
This equation ensures that all points on the circle are exactly units away from the center.
