Answer:
Step-by-step explanation:
Second term = -12; d = 5
First term = -12 - 5 = -17
nth term = a + (n-1)*d
= -17 + (n-1)*5
= -17 + 5n - 5
= -22 + 5n

Step-by-step explanation:
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
