The answer would be 14.14 cu inches. To arrive at this answer, use the formula 4 x pi x r3/3 where r3 is the radius cubed and pi is 3.14. Since the diameter is 3 then the radius is 1.5 inches and the r3 is 3.375. So then 4 x 3.14 x3.375/3 = 14.14.

Vedmedyk [2.9K]

Answer:

The correct response is that from Louisiana someone would probably use the word "coke" when asking for a soft drink.

Explanation:

There is quite a marked regional variation in what words most Americans use for a generic soft drink. In the midwest and the northwestern United States, the word "pop" is used. In the Deep South and states like Louisiana which is where Acadiana was located historically, they tend to use "coke" to refer to a generic soft drink.  In the southwest they use the word "soda," and it is also common to hear "soda" used in the Carolinas and Virginia and in the northeast. Florida shows a mixture of use of the word "soda" or "coke."
