Question Analysis
The main focus is to determine if point lies on circle . We need to find the radius of circle and then calculate the distance between the center and point . If the distance equals the radius, the point lies on the circle.
Key Concept Explanation
1. The radius of a circle is half of the diameter.
2. The distance between two points and in the coordinate plane is given by the formula . A point lies on a circle if the distance from the center of the circle to the point is equal to the radius of the circle.
Step - by - Step Solution
1. Find the radius of circle :
Given the diameter , the radius .
2. Calculate the distance between the center and point
