The volume of a cylinder below 4cm in height v = π v = π v=π *r ^2 *4=28.26.

The volume of the upper half cylinder with a height of 2 cm is v = 0.5 * π * r 2 * 2 = 7.065 (the upper half is obliquely cut from the middle, so the volume after cutting is half of the original).

The total volume is 28.26+7.065=35.325.
