Answer: the cost of the steel per square 0.03m
Step-by-step explanation:
The formula for determining the total surface area of a cylinder is expressed as
Total surface area = 2πr² + 2πrh
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Total surface area = 56π
Radius = Diameter/2
radius = 12/2 = 6
height = 8 feet
Therefore,
Area = 2 × 3.14 × 6² + 2 × 3.14 × 6 × 8
Area = 226.08 + 301.44
Total surface area = 527.52
Suppose the total cost of the steel will be $17,408.16. the steel cost per square meter is
527.52/17408.16 = 0.03
Answer:
-3
Step-by-step explanation:
/= negative slope; \= positive slope
The y-intercept is 2 because this is where it crosses the y-axis
Then you find the next point that touches the graph on an exact point which is (-2,-4)
So, your points are (0,2) and (-2,-4) then you do the slope formula of y2-y1 divided by x2-x1
-4-2/-2-0 = 3 and because the line is / then it is -3
Answer: y = -5x + 4

Answer:
The equivalent factored form of this equation is (x² + 49)(x - 6)
Step-by-step explanation:
<em>x³ - 6x² + 49x - 294</em>
First, group the first and second terms together and group the last two terms together.
<em>(x³ - 6x²) + (49x - 294)</em>
Find the greatest common factor of both parentheses and factor them.
x²(x - 6) + 49(x - 6)
Now, since the two terms in the parentheses are the same, then we have factored the equation correctly.
So, the factored form of the equation is (x² + 49)(x - 6)
