The diagram depicts a toy. The toy has the form of a cone with radius 4 cm and height 9 cm, placed on a hemisphere with radius 4 cm. Diagram is NOT TO SCALE.
Formulae given:
The volume, $V$, of a cone with radius $r$ and height $h$ is $V = \frac{1}{3}\pi r^2 h$.
The volume, $V$, of a sphere with radius $r$ is $V = \frac{4}{3}\pi r^3$.
