What is the range of r coordinate in Spherical Coordinate System?

r coordinate of any point is the distance from Origin.

For example, consider two points P and Q whose r coordinates are shown in the figure.

So obviously, at the maximum, point can be at infinity. And at the minimum, point can be itself an origin with ZERO distance.

So the limit of r coordinate is from ZERO to INFINITY.
