Cavalieri's Principle states that the volume of an oblique cylinder is equal to the product of the area of the base and the height. Mathematically, this can be expressed as, volume = Bh V = (πD²/4)h where D is diameter and h is the height. Substituting the known values from the given above, 486 cm³ =((π)(9 cm)²/4) x h The value of h from the generated equation is equal to 7.64 cm. Thus, the height of the oblique cylinder is approximately 7.64 cm.
