Answer:

B:  10.75 in^3

Step-by-step explanation:

Let's compare the formulas for the volume of a cylinder and the volume of a cone, where the radii and the height of one are the same as the radii and the height of the other:

cylinder:  V = pi*r^2*h

cone:       V = (1/3)pi*r^2*h

Thus, in this problem the volume of the cone is one third of 32.35 in^3, or 10.78 in^3.  Answer B  is closest to this result.
