Answer:
It will cost $39,337.92 for the piller.
Step-by-step explanation:
Given that,
The diameter of the cylinder, d = 8 m
Height of the cylinder, h = 9 m
If concrete cost $87 per cubic meter, we need to find how much the concrete cost for the pillar.
The volume of the cylinder is given by :

Cost per cubic meter = $87
Cost for 452.16 m³ will be :
C = 452.16 × 87
C = $39,337.92
Hence, it will cost $39,337.92 for the piller.
Answer:
10 + (-14) = -4
Step-by-step explanation:
Given that,
Diamond used a number line to add. She started counting at 10, and then she counted until she was on the number −4 on the number line.
For addition, she will add 10 and (-14) as follows :
10 + (-14) = -4
So, the crrect option is (b) "10 + (-14) = -4".
Answer:
x = ±3
Step-by-step explanation:
2 = |x| - 1
Add 1 to both sides: |x| = 3
⇒ x = ±3
