The Area Of The Circle

Answers

Answer 1

The area of the circle formula --> [tex]\pi r^2[/tex]

[tex]\pi[/tex] ≈ 3.14r: length of radius --> 7km

            Length of radius is half of diameter which is 14km long

        [tex]Area = \pi r^2=\pi (7km)^2=(49\pi )km^2=153.86km^2[/tex]  

Hope that helps!

Answer 2

[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]

Let's find the Area of given circle ~

Area of circle is :

[tex] \qquad \tt  \dashrightarrow \: \pi{r}^{2} [/tex]

where, r = radius

[tex] \tt r = d/2 = 14/2 = 7 km [/tex]

Now, let's calculate it ~

[tex] \qquad \tt  \dashrightarrow \: a = \pi{}^{}×(7)² [/tex]

[tex] \qquad \tt  \dashrightarrow \: a = 49\pi{}^{}km² [/tex]

That's the answer I terms of π, but we can also plug in the appropriate value of pi as 3.14

[tex] \qquad \tt  \dashrightarrow \: a=49\times 3.14{}^{} [/tex]

[tex] \qquad \tt  \dashrightarrow \: a= 153.86 \: \: km²[/tex]

[tex] \qquad \tt  \dashrightarrow \: area \approx 154\: \: km²[/tex]

Answers

Answer:

v = 10 yd

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 10 , h = v and A = 50 , then

[tex]\frac{1}{2}[/tex] × 10v = 50

5v = 50 ( divide both sides by 5 )

v = 10

the area of a square 16/36sq foot how do u get side length of the sq?​

Answers

We know that, the area of a square with side being s, is given by s², so if we here assume our side of square whose area is (16/36) sq. foot being s, so we will be having :

[tex]{:\implies \quad \sf s^{2}=\dfrac{16}{36}}[/tex]

[tex]{:\implies \quad \sf s=\pm \sqrt{\dfrac{16}{36}}}[/tex]

But, as length can never be -ve, so we will be taking only +ve length, and if we solve further for s, it will yield ;

[tex]{:\implies \quad \sf s=\sqrt{\dfrac{16}{36}}}[/tex]

[tex]{:\implies \quad \sf s=\dfrac{\sqrt{16}}{\sqrt{36}}}[/tex]

[tex]{:\implies \quad \sf s=\dfrac46}[/tex]

[tex]{:\implies \quad \boxed{\bf{s=\dfrac{4}{6}=\dfrac{2}{3}}}}[/tex]

Well, you might be thinking that (2/3)² willn't give (16/36) rather it will give (4/9), so for this, I'm telling that (2/3) ≈ 0.66666...7 and (4/6) ≈ 0.66666...7, so it's just the same thing and also, (16/36) and (4/9) are just too the same thing, dividing the numerator and denominator of (16/36) will just lead to (4/9) as same as (2/3)²

please I need to know this answer identify and calculate the perimeter for the quadrilateral​

Answers

Step-by-step explanation:

but that is really, really simple.

is the problem that you don't know what a perimeter is ?

a perimeter is the whole distance you have to "walk", if you would "go" around the whole object.

that means you would have to go along every side until you reach the starting point again.

therefore, the perimeter is simply the sum of all side lengths.

P = 8.6 + 3.1 + 6.67 + 5.37 = 23.74 yds

the height does not play any role in this (but it would be important to calculate the area).

I don't understand these huge numbers you have there in the " P =" line.

After performing 1 simulation as the first step in her significance test, Emma does 99 more. For each simulation, she randomly reorganizes the subjects into two groups, A and B, of size 25. In the simulations, group A always plays the role of the treatment group and group B the role of the control group.

After each simulation, she subtracts the average for group B from the average for group A. The distribution of the differences for all 100 simulations is shown in the histogram.

In the original experiment, the average for the treatment
group was 1.6 higher than the average for the control group.
In what percentage of simulations is the average for group A at least 1.6 higher than the average for group B?

Answer Choices:

A: 1
B: 5
C: 1.6
D: 2

Answers

Using the histogram, it is found that the percentage of simulations is the average for group A at least 1.6 higher than the average for group B is given by:

A: 1.

What is an histogram?

An histogram is a graph that shows the number of times each element of x was observed.

In this problem, the histogram shows that out of the 100 simulations, only 1 had a difference of at least 1.6, as the bin corresponding to [1.6, 2] has value of 1 and the bins to the right of this have values of 0.

Hence, the percentage is given by:

P = 1/100 x 100% = 1%.

Which means that option A is correct.

So in total there are 4 cards that we want out of 52.

So the probability of getting a red five or a black six is 4/52 or 1/13

This is an or question. You can choose either one; both are possible and the smaller probability add.

Red 5: 2/52

There are 26 red cards. 2 of them are 5s (diamonds / hearts). You are still drawing from a complete pack of 52

Black 6: 2 / 52

There are 26 black cards. 2 of them are 6s (Clubs / spades). You are still drawing from a complete pack of 52

2/52 + 2/52 = 4/52

By forming two equations and solving them, find how much Laura pays for the 2 tennis balls and 4 golf balls.

Answers

Base on the equation, the amount Laura pay for 2 tennis balls and 4 golf balls $8

How to form and solve equations?

Sam buys 4 tennis balls and 12 golf balls for a total of £19.

let

x = price of each tennis ball

y = price of each golf ball

Hence,

4x + 12y = 19

Luke buys 6 tennis ball and 10 golf balls for a total of £22.50. Hence,

6x + 10y = 22.50

Combine the equation

4x + 12y = 19

6x + 10y = 22.50

6x + 18y = 28.5

6x + 10y = 22.50

8y = 6

y = 6 / 8

y = $0.75

6x + 10(0.75) = 22.50

6x + 7.5 = 22.50

6x = 22.50 - 7.5

6x = 15

x = 15 / 6

x = $2.5

The cost when Laura pays for 2 tennis balls and 4 golf balls is as follows:

Which point is located at (-1, 1 1/4)

A
B
C
D​

Answers

Answer: Point A.

Step-by-step explanation: To find the location of points such as (-1, 1 1/4), you need to know what part of the point is the x-axis and the y-axis.  The first part of the point is the x-axis, which is the horizontal line that goes left to right on the coordinate graph.  The first part of the point (-1, 1 1/4), is -1. The second part of the point is the y-axis, which is the vertical line that goes up and down on the coordinate graph.  The second part of the point (-1, 1 1/4), is 1 1/4. Therefore, we first find the x-axis to the point (-1, 1 1/4), which is -1, and so far, point A is the only option that matches.  However, we need to make sure that the point (-1, 1 1/4)'s y-axis matches to point A as well.  The y-axis to the point (-1, 1 1/4) is 1 1/4 so we need to go up 1 1/4 times, and the point that matches these actions is point A.  Therefore, that's your answer.
