Simply put all values in formula.

Time period = 2*π*(4^2/9.80665*0.725)^1/2.

Ans = 3π

Time period = 2π (K^2/GM. g).

Where, K = Radius of gyration.

GM = Metacentric height.

T = 2π (4^2/0.725x9.81) = 3π answer.

Here 2π(K^2/M.t x g)^.5.

Time period = 2Π (K^2/GM* g)^0.5.
T=2Π (4^2/0.725*9.81)^0.5,
T=2Π *(16/7.11)^0.5,
T=2Π *2.25^0.5,
T=2Π *1.5,
T=3Π -> ANS.

Agreed @Kanji Dodiya.

Mukul Paul said: (Aug 27, 2019)  
Time period = 2π*{k^2/GM*g}^0.5.
