The figure is a composite figure, and the volume is C.20π cm³
How to determine the volume?
The given parameters are:
- Cones = 2
- Cylinder = 1
- Diameter (d) = 4
- Heights (h) = 3
The volume of the figure is calculated using:
V = 2 * Cone volume + Cylinder volume
So, we have:
V = 2/3π(d/2)²h + π(d/2)²h
This gives
V = 5/3π(d/2)²h
Substitute known values
V = 5/3π * (4/2)² * 3
Evaluate
V = 20π
Hence, the volume of the figure is 20π
