Answer:
[tex]V_{sphere}=\frac{4}{3} \pi r^{3}[/tex]
[tex]V_{cone}=\frac{1}{3}\pi r^{2} h[/tex]
Step-by-step explanation:
The formulas you need to use depends on the volumes involved.
A composite figure can be formed by different types, it can be a cylinder with an sphere, a cone with a prism, or a pyramid with an sphere.
So, to solve this problem you need to know how to identify figures and their volume formulas.
Let's say that the composite figure is formed by a sphere and a circular cone. That means you must use the following formulas
[tex]V_{sphere}=\frac{4}{3} \pi r^{3}[/tex]
[tex]V_{cone}=\frac{1}{3}\pi r^{2} h[/tex]
Where [tex]r[/tex] represents radius and [tex]h[/tex] represents height.
Therefore, in this case, you would use those two fomulas.
