Can someone please explain the area of a circle in the simplest way possible, no links

Answers

So, for the area of a circle, there should be a line in the middle. Correct?

Well, that line is the diameter. Then cut that in half, so if the diameter is 6, the radius is 3.

Then multiply the the radius by the radius, so 3x3 once you get that, multiply the answer by pi. Pi= 3.14, so if you do 3x3x3.14 you should get 28.26. Hope this helps.

What are the dimensions of the rectangle?
A rectangle has an area of 40 square units. The length
is 6 units greater than the width
O 8 by 5
10 by 4
11 by 9
13 by 7

Answers

Answer:

its b

Step-by-step explanation:

The requried dimensions of the rectangle are 10 by 4. Option B is correct.

What is a rectangle?

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

Here,
To solve the problem, we can use the formula for the area of a rectangle, which is:

area = length x width

We also know that the length is 6 units greater than the width, which we can express as:

length = width + 6

We can substitute this expression for length into the formula for area, giving us:

area = (width + 6) x width

area = width² + 6width

We are given that the area is 40 square units, so we can set up the equation:

40 = width² + 6width

We can rearrange this equation into the standard quadratic form:

width² + 6width - 40 = 0

We can then use the quadratic formula to solve for the width:

width = (-b ± √(b² - 4ac)) / 2a

Plugging in the values of a, b, and c from the quadratic equation above, we get:

width = (-6 ± √(6² - 4(1)(-40))) / 2(1)

width = (-6 ± √(196)) / 2

width = (-6 ± 14) / 2

So we have two possible values for the width:

width = (-6 + 14) / 2 = 4

or

width = (-6 - 14) / 2 = -10

Since the width cannot be negative, we can reject the second solution. Therefore, the width of the rectangle is 5 units.

We can use the expression for the length in terms of the width to find the length:

length = width + 6 = 4 + 6 = 10

Therefore, the dimensions of the rectangle are 10 by 4.

c = 9.4m is the answer

Step-by-step explanation:

a (length of the telephone pole) = 9m

b (distance between the pigeon and the pole) = 3m

c = ?

According to the Pythagorean theorem,

a² + b² = c²

9² + 3² = c²

81 + 9 = c²

c² = 90

c = 9.4m

∴ the pigeon will fly 9.4m

Margaret Thatcher, Joe Lieberman, John McCain, Charles Krauthammer and other notables offered variations of The Economists cover headline: The Man Who Beat Communism.Actually, Jack F. Matlock Jr. writes in Reagan and Gorbachev, it was not so simple. . . . . In both the title of his memoir and the story it tells, he gives co-star billing to Mikhail Gorbachev.Reagan himself went even farther. Asked at a press conference in Moscow in 1988, his last year in office, about the role he played in the great drama of the late 20th century, he described himself essentially as a supporting actor. Mr. Gorbachev, he said, deserves most of the credit, as the leader of this country.Excerpt from Strobe Talbotts 2004 review of Reagan and Gorbachev: How the Cold War Ended by Jack F. Matlock Jr., the senior coordinator of policy toward the Soviet Union under President Reagana) Identify ONE specific example of how historians might argue that the end of the Cold War was attributable to Reagans policies and US pressure.b) Identify ONE specific example of how historians might argue that the end of the Cold War was attributable to Gorbachevs leadership.c) Identify ONE reason (other than partisanship), based on the events of the last decade of the Cold War, that historians might still debate the respective influences of Reagan and Gorbachev on the end of the Cold War.A) One specific example of how historians might argue that the end of the Cold War was due to Reagans policies and US pressure is the fact that during his presidency, he increased relations with the Soviet Union, while simultaneously building up the American army as both a backup plan and to prepare for a potential arms race, which put pressure on the Soviet Union. Reagan also proposed treaties between the USSR, simultaneously putting pressure on the USSR, essentially forcing them to enter into some sort of treaty or else they will enter an arms race that they likely wouldnt win.B) One specific example of how historians might argue that the end of the Cold War was a result of Gorbachevs leadership was the fact that he instituted a lot of reforms that made the country more capitalist than before, and also more democratic, which pleased the rest of the world and increased foreign relations. He attempted to ease tensions within the country and its satellite states, and started to distance the country from authoritarian rule to move towards a system more suitable for the current world. These new reforms increased foreign relations, and led to the end of the Cold War. C) One reason that historians might still debate the respective influences of Reagan and Gorbachev on the end of the Cold War is that fact that while they both contributed to it, there were a lot of other factors at play during that time period. It is often stated by historians, particularly in this case some historians at The Belfer Center at the Harvard Kennedy School in Cambridge, Massachusetts, that even if Gorbachev had not instituted the reforms that he did, the communist ideology would likely have still dissolved in the USSR. So even if Gorbachev didnt become president and put those reforms in place to decrease the influence of the communist ideology of the people, it still would have likely happened anyway. On the other hand, one could argue that Reagan didnt have much of an influence on the end of the Cold War either, as he himself even states that without Gorbachev, the end of the Cold War wouldnt have been possible. He simply made decisions that were advantageous at the time that were essentially put in place for him. Those are both sides of the argument that many historians have about the influence of each leader on the end of the Cold War. plzzzz helpIn your journal, practice a PATTR + PASAFE of "Small Change: Why the Revolution Will Not Be Tweeted" by Malcolm Gladwell from The Language of Composition.
