Answer:
Full drum 80 dollars
one lid missing
earn 10 dollars less
Step-by-step explanation:
We need to find the surface area
SA = 2 pi r^2 + 2 pi rh
The diameter is 2 so the radius = 2/2 =1
SA = 2 * pi * 1^2 + 2 * pi * 1 * 3
= 2 pi + 6pi
= 8pi
Using pi = 3.14
SA = 8 *3.14 = 25.12 ft^2
We get 3.18 per ft^2
25.12 * 3.18 =79.88
To the nearest dollar
80 dollars
If one of the lids is missing
SA = pi r^2 + 2 pi rh
pi + 6pi
7 pi
Using pi = 3.14
SA = 7 *3.14 = 21.98 ft^2
We get 3.18 per ft^2
21.98 * 3.18 =69.90
To the nearest dollar
70
The difference is 10 dollars
Answer:
y = 7x - 33
Step-by-step explanation:
Using a given point and slope, we need to use point-slope form.
m= 7 (slope)
= 3 (x value from given point)
= -12 (y value from given point)
Now we Substitute values in
Double negative with - (-12) makes 12 positive
Use distributive property for 7(x -3)
Subtract 12 from both sides
You move the decimal to the left three places, so it is 10³
2.5 * 10³
