cylinder volume = π * radius2 * height

cylinder volume = π * 32 * 19

cylinder volume = 171π cubic inches

 

sphere volume = 4/3 * π * radius3

sphere volume = 4/3 * π * 33

sphere volume = 36π cubic inches

 

cylinder volume - sphere volume

= 171π cubic inches - 36π cubic inches

= 135π cubic inches

≈ 424.1 cubic inches
