Radius of gyration means Underroot value of moment of inertia(I) and area(A). Mathematically, radius of gyration(K) is given by, K=I/A but, I and A are in underroot sign.

it is the distance of center of gyration of figure from its axes of rotation.

It is the radius of a ring having same mass & will produce equal moment of inertia as of that actual object.

Radius of gyration or gyradius refers to distribution of the components of an object around an axis. In terms of mass moment of inertia, it is the perpendicular distance from the axis of rotation to a point mass (of mass, m) that gives an equivalent inertia to the original object(s) (of mass, m).
