**Q6: **

A piece of chocolate is in the form of a right cone;
its volume is cm^{3},
and the perimeter of its base is cm.
Find its height.

**Q8: **

A model of a volcano constructed for a science project is cone-shaped with a
diameter of 30 cm.
If the volume of the model is about 2,614 cm^{3},
find the height of the model to the nearest hundredth.

**Q9: **

The capacity of a conical flask is 918 mL, and its height is 15.6 cm. Determine its baseβs radius to the nearest tenth.
