<span> x=8+4t
y=-1+8t
t = 0 x = 8 y = -1
</span>
t = 1 x = 12 y = 7
t = 2 x = 16 y = 15
You have to divided 11 by 2 in order to get the radius
And you’ll get 5.5
r=5.5
h=12
Your formula is (1/3)(pi)(r^2)(h)
Answer:
<em>The largest rectangle of perimeter 182 is a square of side 45.5</em>
Step-by-step explanation:
<u>Maximization Using Derivatives</u>
The procedure consists in finding an appropriate function that depends on only one variable. Then, the first derivative of the function will be found, equated to 0 and find the maximum or minimum values.
Suppose we have a rectangle of dimensions x and y. The area of that rectangle is:

And the perimeter is

We know the perimeter is 182, thus

Simplifying

Solving for y

The area is

Taking the derivative:

Equating to 0

Solving

Finding y

The largest rectangle of perimeter 182 is a square of side 45.5
The answer is 69 , because it just cancels out the numbers
