Answer:
228 cm²
Step-by-step explanation:
The volume of a cylinder of radius r and height h is given by ...
V = πr²·h
Filling in the given information, we can solve for r:
235.5 = π·r²·12
√(235.5/(12π)) = r ≈ 2.49937 . . . . cm
The area of a cylinder is given by ...
A = 2πr² + 2πrh = 2πr(r +h)
Filling in the radius and height, we can find the area to be ...
A = 2π·2.49937·(2.49937 +12) ≈ 227.698 . . . . cm²
About 228 cm² of aluminum are required to make a typical soda can.

Answer:
95% Confidence interval: (14.4537 ,15.1463)
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 15 feet
Sample mean, 
= 14.8 feet
Sample size, n = 16
Alpha, α = 0.05
Sample standard deviation, σ = 0.65 feet
Degree of freedom = n - 1 = 15
95% Confidence interval:
Putting the values, we get,
is the required confidence interval for the true mean length of rods.
The overall length is given as 22.
The line is split into 2 parts X and 3X.
So we have X + 3X = 22
Add X and #X to get 4X:
4X = 22
Divide both sides by 4 to get X:
X = 22 /4
X = 5.5
Now we know what X is so now replace x with 5.5 and solve for LM:
LM = 3X = 3*5.5 = 16.5
Its DBC, cause two is in that point so you just find the answer choice with those three letters in the right order.
