Answer:

See explanation

Explanation:

The combined shape consists of two hemispheres with radius of 2 mm and a circular cylinder with base radius of 2 mm and height of 10 mm.

Find the volume for each individual shape:


V_(hemisphere)=(1)/(2)\cdot (4)/(3)\cdot \pi r^3=(2)/(3)\cdot \pi\cdot 2^3=(16)/(3)\pi \ mm^3


V_(cylinder)=\pi r^2h=\pi \cdot 2^2\cdot 10=40\pi \ mm^3

Find the composite volume of the original figure:


V{combined \ figure}=\\ \\=2V_(hemisphere)+V_(cylinder)=\\ \\=2\cdot (16)/(3)\pi +40\pi =\\ \\=(32)/(3)\pi +40\pi =\\ \\=(152)/(3)\pi \ mm^3
