Question author, it's spelled pi not pie, and we use just use the Greek letter π. Students, demand better from your teachers.
1. Rectangular prism, aka a box. Volume is length times width times height.
V = 5×7×9 = 315 cubic feet
That's cubic feet of course, the product of three lengths. We didn't even need to do the problem, just look for the common answer and pick the one with the right units. I just saw that same pattern in a volume problem yesterday.
Answer: 315 cubic feet, first choice
2. Cylinder, volume is base area times height, πr²h. We have a radius of r=14/2=7 yd and h=8 yd. We're using π=3.14.
V = πr²h = 3.14(7²)(8) = 1230.88 cubic yds
Answer: 1230.9 cubic yards, last choice
If you let x = 13:
Then, Area = 2(13)^2 - 5(13)
= 338 - 65
= 273 sq ft
If you let 2x-5 = 13:
2x = 18
x = 6
Then, Area = 2(6)^2 - 5(6)
= 72 - 30
= 42 sq ft
Therefore, your options are A or C. Your answer can be chosen based on what you assume the width to be. Good luck!
Answer:

Answer:
b. $146,000
Step-by-step explanation:
1 usd = 146 jmd
1000 = ___ jmd
We multiply 1000 and 146:
1000($146) = $146,000
