Answer:
A = 59.63cm^2
Step-by-step explanation:
You have the following function for the surface area of the container:
(1)
where r is the radius of the cross sectional area of the container.
In order to find the minimum surface are you first calculate the derivative of A respect to r, to find the value of r that makes the surface area a minimum.
(2)
Next, you equal the expression (2) to zero and solve for r:
Finally, you replace the previous result in the equation (1):
The minimum total surface area is 59.63cm^2
The equation, in point-slope form of the line that is parallel to the given line and passes through the point (-1, -1) is y + 1 = 3(x + 1).
<u>Solution:</u>
Given that, a line passes through (0, -3) and (2, 3).
We have to find the line equation which is parallel to above line and passes through (-1, -1).
Now, let us find the slope of the given line.
So, slope of given line is 3,
Then, slope of required line is also 3, as slopes of parallel lines are equal.
Then, required line equation in point – slope form is given as:
Hence, the line equation is y + 1 = 3(x + 1).
