Answer:
71.21 in³
Explanation:
Seeing as these two objects don't have anything extra on them, we can assume that we just have to add up the two separate volumes of the sphere and cylinder to get the total object's volume.
The volume of a sphere is (4/3)πr³, so we plug 2 in for the radius, r, and get approximately 33.51.
The volume of a cylinder is πr²h, so we plug 3 in for the height and 2 in for the radius (4 inches is the diameter, and the radius is half of that) to get approximately 37.70
Add our two volumes up to get 71.21 in³ as our answer
