Expert Answer:

Dear student

Radius of gyration is the distance, from the axis of rotation of a body to a point where the whole mass of a body may be considered to be concentrated. It is given by

k = (I/m)1/2

where I is the moment of inertia of body of mass m about the axis of rotation.
Hope this helps.
