We need to assume that the can of soda can be represented as a cylinder. Then we use the formula for a cylinder volume and that's it.
The volume of a cylinder is given by:

Where r is the radius of the base and h the height of the can.
If we reply the measures in this equation we have:

So we can conclude that the volume of the can of soda is 19.5 in³, thus the correct answer is A.
