ANSWER:3.3M2

 

                                                        

Step-by-step explanation:

Let r be the common radius of the cylinder and hemisphere and h be the height of the hollow cylinder. 

Then r=30cm;h=1.45m=145cm

Total surface are of the bird-bath = curved surface area of the cylinder + curved surface area of the hemisphere

                                                        =2πrh+2πr2

                                                        =2π(h+r)

                                                        =2×722×30(145+30)cm2

                                                        =3.3m2
