It appears you have a complete sphere of radius 4 cm when you consider the hemispheres at each end of the cylinder.
So, we're dealing with the volume of a sphere plus the volume of a cylinder.
Find the volume of the sphere: , using r = 4.
Now, the cylinder between the two hemispheres has a height that is 8 centimeters less than the height (length) of the container which was 22 cm.
You have to subtract the radii of the two hemispheres from 22 cm. to get a cylinder height of 14 cm.
Now find the volume of the cylinder using using r = 4 and h = 14.
Finally, add the volume of the cylinder to the volume of the sphere.
