Question

solve the problem in attachment

Answer 1

$\mathbb{\green{\huge{SEE\:THE\: ATTACHED \:PICTURE}}}$

Answer 2

volume of hemisphere is 2/3 pi r3

radius = 18 cm

so putting value keep pi as it is

2/3 * pi * 18 * 18 * 18 = 1888 pi

now volume of cylinder

= pi r2h

pi * 3 * 3 * 6 = 54 pi

now number of bottles required can be taken as n

so

n * 54 pi = 3888 pi

pi cancels

n = 3888/ 54  = 72 bottles

hope you understood my friend
