<span>The arc markings are actually used as the baseline in
determining the center and the radius of the circle. The arc markings are
created with the use of a compass. All other choices are completely irrelevant
because what we need is the arc and not the angles. The angles do not create
the circle. Letter C is also wrong because what we are trying to form is the
circle and not the triangle. The triangle is already created.</span>
Answer:
side of 6.124 ft and height of 3.674 ft
Step-by-step explanation:
Let's s be the side of the square base and h be the height of the rectangular box.
The base and the roof would have an area of
and cost of

The sides would have an area of 4sh and cost of 4sh*2.5 = 10sh
So the total cost for the material is



The volume of the shed has the following formula

To find the maximum value for V, we can take its first derivative, and set it to 0




h = 45/s - 0.6s = 3.674 ft
