Answer:
Table B is the correct answer.
Step-by-step explanation:
Answer
Answer: Volume = 9025.8 cm³
Step-by-step explanation:
--------------------------------------------------------
Find Radius :
--------------------------------------------------------
Base area = πr²
169π = πr²
r² = 169
r = √169
r = 13 cm
--------------------------------------------------------
Find height :
--------------------------------------------------------
Height = 13 + 4
Height = 17 cm
--------------------------------------------------------
Find Volume :
--------------------------------------------------------
Volume = πr²h
Volume = π(13)²(17)
Volume = 9025.8 cm³
--------------------------------------------------------
Answer: Volume = 9025.8 cm³
--------------------------------------------------------
Answer:
I have a answer for the second question. The better buy would be 69 cents for 18in. I say this because in each foot there is 12 in right, 18 in is a foot and 6 in. if you buy two 18 in wires it will cost $1.38 for 3 feet of wire which is cheaper then $1.49.

Answer:
The series converges.
Step-by-step explanation:
According to the alternating series test:
For a series ∑(-1)ⁿ aₙ or ∑(-1)ⁿ⁺¹ aₙ
If lim(n→∞) aₙ = 0
and aₙ is decreasing,
then the series converges.
aₙ = n² / (n³ + 1)
Since the power of the numerator is less than the power of the denominator, lim(n→∞) aₙ = 0.
Since n² / (n³ + 1) > (n+1)² / ((n+1)³ + 1), the series is decreasing. (We could also prove this by showing that the derivative is negative.)
Therefore, the series converges.
