The volumes of the given figures are:
- Half-sphere: 2,093.3 m³
- Cylinder: 3,140 m³
- Cone: 1,046.67 m³
<h3>
How to find the volume of the 3 figures?</h3>
First, let's take the half-sphere.
The volume of half a sphere of radius R is:

Where pi = 3.14
In this case, R = 10m, then the volume is:

For a cylinder of radius R and height H, the volume is:

Here w ehave:
R = 10m and H = 10m, then:

For a cone of radius R and height H, the volume is:

Here we have:
R = 10m
H = 10m
So the volume is:
