B, 0.4 in³

Step-by-step explanation:

A cone's volume is determined with the equation 4/3πr²(h/3). In this case, our radius is 0.5 because the diameter is 1, and our height is 3.5 inches. We plug those values into the equation to get approximately 0.92 in³.

Now for a sphere, the volume is determined by 4/3πr². Our diameter is 1, so our radius is 0.5, and pi is 3.14, so plugging that in we get about 0.52

Now we subtract the 2, 0.92 - 0.52 = 0.4

it's both, now can you answer my most recent question?
