If a circle has a radius of 4. then the area of the circle is

Answers

Answer 1

Answer

16[tex]\pi[/tex] or 50.24 units

Explanation:

[tex]\pi[/tex][tex]r^{2}[/tex] and r is the radius, since we know what the radius is (r ) we can put this in to an expression

[tex]\pi[/tex] · 4² = 16 units

If the answer is not 16 then its 50.24 units

Explanation:

Now 16 is the correct answer but just in case I took this a step further.

If we estimate the area by using 3.14 which is ( [tex]\pi[/tex] ) because sometimes that isn't  natural to express the area using [tex]\pi[/tex]

I hope I helped you : )

what are the three types of materials that affect light differently

Answers

Answer:

Explanation:

The purpose of this lesson is for the students to learn that light interacts differently with different types of materials. Students will be able to categorize materials into 3 categories based on how the light interacts with those materials: transparent (light shines through), translucent (some light shines through, and opaque (no light shines through).

Answer:

Glass, plastic, mirrors="If a material is a light colour or has a smooth surface, more light will be reflected. Shiny opaque materials, such as mirrors, reflect most of the light that strikes them. If a material is a dark colour or has a rough surface, more light will be absorbed. Opaque objects that absorb light also become warm."

A square with sides 8 inches in length has a circle inscribed in it. The circle has a radius of 4. What is the area of part of the square not in the circle.

Answers

16π−32

Explanation:  

To get the area inside the circle but outside the square, we simply get the difference of their areas.

Ac=r2π=42π=16πA square is also a rhombus (with equal diagonals), so we can use the formula for the area of the rhombus. What do we use as the value of the diagonal? The diameter of the circle!As=12d1d2=12d2=12(82)=12(64)=32

Hence, A=16π−32 If you think you won't be able to remember the formula of the rhombus, we can go the usual way of getting the area of the square.As=s2Now, we need to find the length of the side. To do this, we can form an imaginary right isosceles triangle with the radius of the circle as legs and the side as the hypotenuse. How do we know the triangle is right? It's a property of a square, the diagonals form a right angle.Now, we use the Pythagorean theorem to get the side,

c2=a2+b2=2a2=2(42)=32⇒c=4√2

Now we can get the area of the square.As

=s2=(4√2)2=32Hence, A=16π−32

Which of the following is not true? Longshore currents always move in the same direction. Wind, waves and tides are among the factors that can affect the direction of longshore currents. Longshore currents frequently move in the same direction as permanent offshore currents. Local dive operators are a good source of information on the behavior of longshore currents.

Answers

Answer: Longshore currents always move in the same direction.

Explanation:

The movement of Longshore currents are affected by a variety of factors such as wind, waves and tides so the second option is a true statement.

Longshore currents generally follow the direction of Permanent offshore currents as they approach the coast so this is a true statement as well.

Local dive operators would have extensive knowledge of the area they work in because it is their job to know so they will definitely be good sources for information on the behavior of Longshore currents so this is another true statement as well.

Longshore currents however DO NOT always move in the same direction. As they are impacted by the factors listed above, they can move in different directions and can even more in reverse.

What interesting patterns did you notice between the various stakeholders in relation to the arguments for and against the Keystone XL Pipeline?

Answers

Hello. You did not submit the text to which this question refers, which makes it difficult for it to be answered. However, I will try to help you as best I can.

Keystone XL Pipeline was a pipeline installation project that originated in Canada but extended to the US. The installation of this pipeline was very controversial and spurred people against and in favor of the installation. It was normal that both the people who were against and those who were in favor presented opinion patterns that are opinions that are repeated in each group.

In the group in favor of installing the pipeline, we could see a pattern where people argued that this pipeline would create many jobs, improve countries' economies, and increase the flow of energy and oil in North America. In the group against installation, we could see a pattern, where people claimed that the installation of this pipeline would negatively impact nature and encourage the use of fossil fuels that would stimulate global warming.

I found a bed bug in my room. I told my mom and she blamed me Bc my room wasn’t clean. Yeah, I been not cleaning up. And she thinks that bed bugs only come at night. So, yesterday I slept in the living room. In the morning I got blamed and she said that’s why you should clean your room. Then I went in my room SCARED Bc my mom told me too, and I’m scared that it would be more. So I went back in the living room, and I felt anxious like I have to throw up. But my mom saw me and said I was being hard headed and I told her I was scared. Then she said that IT NO MORE BED BUGS IT WAS JUST ONE. Also I forgot to tell y’all that my dad look under the my mattress and it wasn’t anymore. BUT BED BUG ALSO HIDE IN OTHER PLACES TOO.

But I need advice, how do I know if there’s anymore bed bugs. Also I never gotten bed bugs before sooo what are the signs? If there is signs what do it look like???

Answers

Answer:

I don't think it was because your room wasn't clean. The main cause of bed bugs is travel, which means most likely you got one on you when you went outside or something, and you accidentally got it into your room. Bed bugs hitchhike on luggage, clothing, people, etc.

If there are blood stains or dark/rusty spots on your bed/pillow, there are definitely bed bugs. The bloodstains/spots come from you crushing the bed bugs accidentally. The place where bed bugs are (in this case, your room), may also begin to smell bad. You might also see eggs laid by the bed bugs.

Let me know if you have any other questions. Good luck!
