given,
internal diameter=36cm
internal radius=36/2=18cm
volume of bowl=2/3 πr³
=2/3(22/7)(18³)
=2×22×18³/7×3
=12219.4cm³
volume of bottle=πR²h
=22/7(3²)(6)
=22×9×6/7
=169.7cm³
no. of bottles required=12219.4/169.7
=72.23=72 bottles approx

hey mate...
A hemispherical bowl of internal diameter 36 cm contains a liquid in cylindrical bottles of radius 3 cm and height 6 cm. How many bottles are required?
Volume of hemispherical bowl
= 2/3 pi radius^3 = 2/3 pi 18^3
= (12*18²)pi cu cm ……….(1)
Volume of one cylindrical bottle = pi radius² h
= pi *9 *6= 54 pi cu cm ……….(2)
So no of bottles = (1) ÷ (2)
= (12 *18²) pi / 54pi
= (12 * 18*18) / (3* 18)
= 4 * 18
= 72 bottles …….ANS
