I don't even actually need to work this one out. The rule between the volumes of a cylinder and a cone is that is they have the same height and diameter, the the volume of the cone is one-third that of the cylinder. But in this case the cone's height is three times that of the cylinder. So I predict that their volumes are the exact same. But working it out, the volume of a cylinder is V=πr2h, and plugging in all the appropriate values the volume of the cylinder is 251.33 square inches. And the volume of a cone is V=πr2(h/3), and plugging in the values given to me here the volume of the cone is 251.33 square inches. Therefore their volume is the same.
The <u><em>correct answer</em></u> is:
B) The cost for a group of friends to see a movie compared with the number of friends
Explanation:
Movie tickets typically cost a specific amount per person. This means that every person you take would add that cost to the total; this would be a constant rate of change, as there would be the same difference between successive points.
Answer:
(9 -5x) + (-9 +5x)
Step-by-step explanation:
-Three times two is six plus three is nine
-Negative three times two is negative six minus three which is negative nine
