The radius of a circular board is 3. 5 meters. If the cost of paint is $4/m2, estimate the cost of painting the board. What is the area of the board?

Answers

Answer 1

The cost of painting the board can be estimated by calculating the area of the board and multiplying it by the cost of paint per square meter. The area of the board is πr², where r is the radius of the circular board.

Given that the radius of the circular board is 3.5 meters, we can calculate its area using the formula A = πr². Plugging in the value of the radius, we have A = π(3.5)². Simplifying this equation, we get A ≈ 38.48 square meters.

To estimate the cost of painting the board, we multiply the area by the cost of paint per square meter. Given that the cost of paint is $4 per square meter, the estimated cost of painting the board would be approximately $4 × 38.48 ≈ $153.92.

In summary, to estimate the cost of painting the circular board, we calculate its area using the formula A = πr², where r is the radius. Then, we multiply the area by the cost of paint per square meter to get the estimated cost.

O A. The Mexican-American War should be considered one of the
greatest victories of the United States.

B. Mexico's economic problems stem from its losses during the
Mexican-American War.

C. The United States gained large amounts of land because of the
Mexican-American War.

D. The United States was wrong to start the Mexican-American War
to achieve Manifest Destiny.

Answers

Answer:

C. The United States gained large amounts of land because of the Mexican-American War.

Explanation:

The United States territory grew by ~1/3 after obtaining ~500,000 sq mi of land from Mexico, not including the Gadsen Purchase which expanded the territories to the current border.

Why the answers can be, but shouldn't be the others:

A) The Mexican-American War is a victory for the United States, but there are much more important wars fought by the United States that had a greater impact to the US itself, as well as the world. Examples of this can be the American Revolutionary War (which led to the creation of the US in the first place), as well as the World Wars, in which the first set the US up as a industrial powerhouse, and the second as a world superpower.

B) A portion of Mexico's economic problems may stem from its losses in war in history with the United States, however, not all of today's problems could or even should be attributed to the US all the way back to the Mexican-American War. Poor government, failure to keep cartels in check, and corruption in both the Mexican police force and military force has led to Mexico having many internal problems.

D) Both sides can be argued on whether or not it was correct for the United States to start a Mexican-American War, as Mexico had previously shown signs of aggression, and the United States simply moved to eliminate the threat as best as possible. However, that is not to say that the United States is not entirely at fault, just that they are not entirely wrong either.

Answers

Answer:

D

Explanation:

The discovery of penicillin significant because it was an effective treatment for bacterial infection.

What is bacterial infection?

When bacteria enter the body, multiply, and trigger an immune response in the body, a bacterial infection results. Through an opening in your skin, such as a cut or surgical wound, or through your airway, germs can enter your body and cause diseases like bacterial pneumonia.

A bacteria is made up of a single complicated cell. It has the ability to endure on its own, inside or outside of the body.

Most bacteria don't cause harm. In fact, our bodies contain a variety of bacteria, particularly in the stomach where they aid in digestion. Some germs, however, can lead to illnesses. Bacterial infections can damage the skin, gut, lungs, throat, and many other body parts. Many are minor; a few are serious.

Bacterial infections can be quite contagious, so you should take extra precautions to prevent infection by washing your hands, covering your mouth and nose when you sneeze or cough, and not sharing drink containers.

With its completion in 1883, it ranks among the earliest suspension bridges in the United States and was the first steel-wire suspension bridge ever built. John Augustus Roebling created the Brooklyn Bridge. He was measuring across the East River ferry when he stomped his foot against a piling.

After having his foot removed, he contracted tetanus, went into a coma, and passed away from the disease 3 weeks later, just a few days after appointing his son Washington Roebling to oversee the bridge's construction.
