Answer:
92.11 cm³
Explanation:
The figure below;
- Has two hemispheres, and
- An open cylinder
- The radius of the hemisphere is 2 mm
- The height of the cylinder is 6 mm (10 mm - 4 mm)
We are required to determine the volume of the figure;
The volume of a hemisphere is given by;
Volume hemisphere = 2/3πr³
Taking π to be 3.14
The Volume of the two hemisphere;
= 2/3 × 3.14 × 2³
= 16.75 cm³
Volume of the cylinder;
Volume = πr²h
= 3.14 × 2² × 6
= 75.36 cm³
Thus, volume of the figure;
= 16.75 cm³ + 75.36 cm³
= 92.11 cm³
Hence, the volume of the figure is 92.11 cm³
