The true statement is David's calculations are incorrect, he used the circumference and the height to find the volume.
<h3>Volume</h3>
Correct calculation:
- Height = 15.2 cm
- Circumference = 8.6 inches
C = 2πr
8.6 = 2 × 3.14 × r
8.6 = 6.28r
r = 8.6/6.28
r = 1.36942675159235 inches
convert 1.36942675159235 inches to cm
= 3.478343949044569 cm
Approximately,
r = 3.5 cm
Volume = πr²h
= 3.14 × 3.5² × 15.2
= 3.14 × 12.25 × 15.2
= 584.668 cm³
Approximately,
volume = 584.7 cm³

Answer:
Step-by-step explanation:
Answer: -1.5y + 10.4
Step-by-step explanation: 8.9 + 3.5y - 0.5 (10y - 3)
I hope this helps!
Answer:
y = 1 x = 3
the +1 at the end of the equation is the y intercept while the number with the x is the slope, since the slope is -1/3 take it as if it was rise/run. In other words since the rise is -1 you are going down 1 unit and the run is 3 you are going 3 units to the right & that's the path its going to be taking. So that makes the line cross the x axis at (0,3)
The formula of a volume is V = l*w*h
The prism is 4 cm long, 1.4 cm wide, and 3 cm tall.
4 * 1.4 * 3 = 16.8
The volume is 16.8 cubic cm.
