Question Analysis
The main focus is to determine if point lies on circle . We'll calculate the distance between the center and point using the distance formula. Then, we'll compare this distance to the radius of the circle. If the distance equals the radius, the point lies on the circle.
Key Concept Explanation
The distance between two points and in the coordinate plane is given by the formula . For a circle with center , a point lies on the circle if the distance from the center to the point is equal to the radius.
