Detailed explanation-1: -The center of a circle is the point equidistant from the points on the edge. Similarly the center of a sphere is the point equidistant from the points on the surface, and the center of a line segment is the midpoint of the two ends.

Detailed explanation-2: -Solution: The center of the circle equation is (x-h)2 + (y-k)2 = r2.

Detailed explanation-3: -In reality, if you use a compass to draw a circle it obviously has a beginning point where you started to draw it. However, if you accept the mathematical definition of a circle as the set of points equidistant from a given point called its center. Then in the pure mathematical world, the circle has no beginning.

Detailed explanation-4: -While the circle has no beginning or end, the curve, as part of the circle, can insinuate a direction and orientation, and can also imply movement.
