A hemispherical bowl of internal radius 15 cm contains a liquid.

Internal radius of hemispherical bowl r = 15 cm

The volume of bowl $=\frac{2}{3} \pi r^{3}=$ volume of liquid $=\frac{2}{3} \pi(15)^{3}$

Volume of liquid $=2250 \pi \mathrm{cm}^{3}$

Since, the liquid filled into the cylindrical shaped bottles of radius $\frac{5}{2} \mathrm{~cm}$ and height $6 \mathrm{~cm}$.

Let n be the no. of bottles.

Therefore,

The volume of liquid = n × volume of cylindrical shaped bottle

$2250=n \times \frac{25}{4} \times 6$

$n=\frac{2250 \times 4}{25 \times 6}$

$=60$

$n=60$

Hence, the no. of bottles = 60
