In the first question firstly, We will find the volume of the hemisphere with a diameter of 8 cm.

We will find the volume of the hemisphere by using the formula that is,[tex]2\pi r ^{3}/3[/tex].

Which gives us, [tex]134.09 cm^{3}[/tex].

Now we will find the volume of the inverted cone with the formula,[tex]\pi r^{2}h/3[/tex].

Which gives [tex]50.28 cm^{3}[/tex].

Adding both give [tex]184.57 cm^{3}[/tex].

Rounding [tex]184 cm^{3}[/tex]

In the second question firstly, We will find the volume of the hemisphere with a radius of 3cm.

we will find the volume of the hemisphere by using the formula that is,    [tex]2\pi r^{3} /3[/tex].
