The radius of the hemispherical bowl = r = \frac{10.5}{2}\ cm

We know, Volume of a hemisphere = \frac{2}{3}\pi r^3

The volume of the given hemispherical bowl = \frac{2}{3}\times\frac{22}{7}\times \left (\frac{10.5}{2} \right )^3

= \frac{2}{3\times8}\times22\times1.5\times10.5\times10.5

= 303.1875\ cm^3

The capacity of the hemispherical bowl = = \frac{303.1875}{1000} \approx 0.303\ litres\ \ \ (approx.)
