The volume of a cylinder is the area of the base times the height, so 
. The volume of a sphere is 
, and a hemisphere is half of a sphere so, 
.
The volume of a cylinder and a hemisphere together is the sum of the two volumes, so:
You can do a little algebra to simplify the arithmetic:
)
Plug in the given values and do the arithmetic. Remember you are given the diameter which is two times the radius.
