This method can only be used for questions which have to do something with concave mirror.
relation between radius of curvature of a concave mirror and its focal length is that
=> radius of curvature = 2×( focal length)
given focal length is 20cm.
=> radius of curvature = 2×( 20)
=> radius of curvature = 40cm.
