The maximum volume will be obtained when it is rotated about the smaller side rather than the hypotenuse.

Radius = 8 units and the height = 6 units.

Thus, the volume = (1 / 3) x (π x 64 x 6) = 128π units.

Hence, option 4.

Radius = 8 units and the height = 6 units.

Thus, the volume = (1 / 3) x (π x 64 x 6) = 128π units.

Hence, option 4.
