Explanation:
Detailed explanation-1: -According to the distance formula, this is √(x−0)2+(y−0)2=√x2+y2. A point (x, y) is at a distance r from the origin if and only if √x2+y2=r, or, if we square both sides: x2+y2=r2. This is the equation of the circle of radius r centered at the origin.
Detailed explanation-2: -Precalculus Examples. The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circumference of the circle.
