Correct Answer: 19404 cm 3


Solution : A hemispherical bowl whose radius is 21 cm is full of ice cream.
We know that the volume of a hemisphere = $\frac{2}{3}\pi r^3$, where $r$ is the radius
So, the required volume of the ice cream = $\frac{2}{3}×\frac{22}{7}×21×21×21$ = 19404 cm 3
Hence, the correct answer is 19404 cm 3 .
