If earth shrinks then the duration of day

If the radius of the earth shrinks by "25%" without change in its mass,the time duration of one day will be "

If the mass of the earth is kept constant and its radius is made half, then the duration of the day will be where T is the present duration of the day.

Statement-1 : When ice on polar caps of earth melts, duration of the day increases. Statement-2 : L = I omega = I ((2pi)/(T)) = constant .

Assertion (A) : Contries like Netherlands, Bangladesh and Maldives face danget of getting submerged. Reason (R) : Due to global warming, polar ice caps melt, increasing the level of sea water.
