Answer:

D. 640 m³

Explanation:

The height CD of the cone is found using the Pythagorean theorem.

BC² + CD² = BD²

8² + CD² = 17²

CD = √(289 -64) = 15

The volume of the cylinder is ...

V = πr²h

The volume of the cone is ...

V = 1/3πr²h

So, the portion of the cylinder not occupied by the cone is ...

V = (πr²h) -(1/3πr²h) = (2/3)πr²h

V = 2/3(π)(8 m)²(15 m) = 640π m² . . . . . matches choice D
