Question Analysis

The main focus is on determining the diameter of the circle. First, we need to find the radius by identifying the center  and a point on the circumference. Then, we use the relationship  (where  is the diameter and  is the radius) to calculate the diameter.

Key Concept Explanation

The diameter  of a circle is twice the radius , i.e., . The radius is the distance from the center of the circle to any point on its circumference, and we use the distance formula  to find it.

Step - by - Step Solution

1. Calculate the radius using the distance formula:

Given the center  and the point on the circumference
