Answer:
530.93 units squared
Explanation:
The formula for the area of a circle is pi*r^2. The radius is half the diameter. So, 26/2 = 13.
pi*13^2 = ?
pi*169 = 530.93
The area is 530.93 units squared.
If the long-run average total cost curve of an industry is declining at the point where it intersects the industry demand curve, then we can expect that the industry will be a natural monopoly.
<h3>
What is Natural monopoly?</h3>
This is characterized by high infrastructural costs and other barriers which prevent entry into the market. This gives rise to a very few being involved and usually offers no competition as there is a single seller with unique types of goods and services.
This type of monopoly involves sellers having a big size and able to produce the required output for the consumers. This makes them to be self-sufficient and is characterized by the long-run average total cost curve of an industry declining and intersecting the industry demand curve which is the reason why it was chosen as the most appropriate choice.

<h3>Young Modulus of a substance</h3>
The young modulus of a substance is the<u> ratio of stress to the strain</u> of material.
where:
- F is the applied force = 5000N
- l is the length of the rod = 5.0m
- A is the cross-sectional area =
