$\large\mathsf{\underline{Hemisphere}}$

$\mathsf{diameter, \ d \ = \ 36 \ cm}$

$\mathsf{radius, \ r \ = \ {\dfrac{diameter}{2}}}$

$\mathsf{radius, \ r \ = \ {\dfrac{36}{2}}}$

$\mathsf{radius, \ r \ = \ 18 \ cm}$

${\boxed{\mathsf{Volume \ = \ {\dfrac{2}{3}} \pi r^3}}}$

$\mathsf{Volume \ = \ {\dfrac{2}{3}} × \pi × (18)^3}$

$\mathsf{Volume \ = \ 2 × \pi × 18 × 18 × 6}$

$\mathsf{Volume, \ V_H \ = \ 3888 \pi \ cm^3}$

$\large\mathsf{\underline{Cylinder}}$

$\mathsf{radius, \ r \ = \ 3 \ cm}$

$\mathsf{height, \ h \ = \ 6 \ cm}$

${\boxed{\sf{Volume \ = \ \pi r^2h}}}$

$\sf{Volume \ = \ \pi (3)^2 × 6}$

$\sf{Volume, \ V_C \ = \ 54 \pi \ cm^3}$

$\sf{A/q}$

$\sf{V_C × No. \ of \ bottles \ = \ V_H}$

$\sf{54 \pi × No. \ of \ bottles \ = \ 3888 \pi}$

$\sf{No. \ of \ bottles \ = \ {\dfrac{3888}{54}}}$

${\large{\boxed{\sf{\blue{No. \ of \ bottles \ = \ 72}}}}}$
