If the radius in a circle is 0 the graph is

WebIn classical geometry, a radius (PL: radii) of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length.The name comes from the latin radius, meaning ray but also the spoke of a chariot wheel. The plural of radius can be either radii (from the Latin plural) or the conventional English plural radiuses. WebSphere's are the 3D representations of circles. The equation of a sphere is similar to that of a circle, but with an extra variable for the extra dimension. (x−h)2+ (y−k)2+ (z−l)2=r2 In this equation, r=radius. The coordinate (h,k,l) tells us where the center of the sphere is. In this video, Krista goes over two types of problems you ...
