Answer:

D. 10

Step-by-step explanation:

The volume of the cylinder is given by the formula ...

V = πr²h

V = π(4 in)²(13 in) = 208π in³

The volume of a cone 3 inches in radius and 7 inches high is ...

V = (1/3)πr²h = (1/3)(3 in)²(7 in) = 21π in³

Then the ratio of the volume of the cylinder to that of the cone is ...

(208π in³)/(21π in³) ≈ 9.905

You would need to fill the funnel about 10 times to fill the can.
