we can see that
there are two hemispheres and one cylinder
so, we will find volume of each
and then we combine them
Hemisphere:
we can see that
diameter=20
so, radius =10

now, we can use volume formula

now, we can plug values


Cylinder:
now, we can find volume of cylinder


we can use formula

now, we can plug values
we get

now, we can find total volume
