By applying the <em>volume</em> formulae for <em>composite</em> figures, cones and hemispheres, we obtain that the volume is approximately equal to 558.9 cubic centimeters.
<h3>How to determine the volume of a composite figure</h3>
The volume of the <em>composite</em> figure is the sum of the volumes of the two figures: (i) a cone, (ii) a hemisphere. The volume formula of the figure is shown below:
If we know that r = 5.3 cm and h = 8.4 cm, then the volume of the composite figure is:
V = (2π/3) · (5.3 cm)³ + (π/3) · (5.3 cm)² · (8.4 cm)
V ≈ 558.900 cm³
