The answer of u r question is....

Ans:

Let,

Height of the conical portion h1=7cm

Then,

Height of the cylindrical portion h2=12cm

Radius(r)=4.2/2=2.1

=21/10 cm

volume of the solid toy...

=Volume of the cone+volume of thd cylinder +volume of the hemisphere..

$= \frac{1}{3} {\pi}^{2} h1 + {\pi}^{2} h2 + \frac{2}{3} {\pi}^{3}$
and please refer the pic...
