Answer:
The volume of oblique cylinder is 252π cm³
D is correct.
Explanation:
We are given a oblique cylinder whose radius 6 and slant height 8, vertical height 7
Volume of cylinder = Base area x vertical height.
Because volume of cylinder can't be change if we change oblique to vertical cylinder.
Base area



Vertical height = 7 cm
Volume of cone


Hence, The volume of oblique cylinder is 252π cm³
