Answer: first multiply then determine if you should add or subtract.
Step-by-step explanation:
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.
Answer:
x=2,y=7
Step-by-step explanation:
Using elimination method:
Add both equations
8x=16
x=2
Put x=2 into equation 2
3•2+6y=48
6y=42
y=7
I don’t know much about the question but it sounds like they both have great ideas and therefore they are alike.
