An engineer wants to know the volume of the following object composed of a hemisphere and a cone. She knows the height of the cone is equal to the diameter of the hemisphere, and the volume of the cone is 12m ^ 3 What is the volume of the whole object? (1 point) 18m ^ 3; 36m ^ 3; 24m ^ 3 There is not enough information to say.

To find the volume of the whole object, we need to know the radius or diameter of the hemisphere. However, the given information only states that the height of the cone is equal to the diameter of the hemisphere. This is not sufficient to determine the specific values needed to calculate the volume. Therefore, there is not enough information to say what the volume of the whole object is.
