Volume of a cone = 1/3 × πr²h. Here, volume = 1/3 × 3.14 × 3 × 3 × 69 = 649.98 cubic cm. A cone has one circular base and tapers to a point, so its volume is one-third of a cylinder with the same radius and height. That is why the formula includes 1/3. The answer is in cubic units, so the correct choice is 649.98 cm³.
