Diameter of hemispherical bowl =$10.5$ cm

Radius of hemispherical bowl, r = $\frac{10.5}{2}$ cm = $5.25$ cm

Formula for volume of the hemispherical bowl = $( \frac{2}{3} ) πr3$

Volume of the hemispherical bowl = $( \frac{2}{3} )×( \frac{22}{7} )×5.253 = 303.1875$

Volume of the hemispherical bowl is $303.1875$ cm3

Capacity of the bowl = $\frac{303.1875}{1000 \: L} = 0.303$ litres(approx.)

Therefore, hemispherical bowl can hold $0.303$ litres of milk.
