Can radius be negative?
Understand the Problem
The question is asking whether the concept of radius can take on a negative value. This often pertains to mathematical and geometric contexts, where radius is typically defined as a non-negative distance from a point to the edge of a circle or sphere.
Answer
The radius of a circle cannot be negative.
The radius of a circle cannot be negative.
Answer for screen readers
The radius of a circle cannot be negative.
More Information
In a standard Euclidean context, a radius is defined as the distance from the center of the circle to any point on its boundary. Distance cannot be negative, hence, a radius cannot be negative. However, in some advanced mathematics or polar coordinates, negative radii might be interpreted differently.
Tips
Avoid confusing distance (always positive) with directional properties in certain coordinate systems.
