Q: Find the area!

Answers

Answer:

113.04 in^2

Step-by-step explanation:

A=pi*r^2

A=3.14*6^2

A=3.14*36

A=113.04

Answer

The area of the circle is [tex]36\pi[/tex] inches squared.

Explanation

The formula for the area of a circle is [tex]\pi r^{2}[/tex]. You are already given the radius (which is 6) so all you have to do is substitute the 6 for 'r' and solve the equation.

After substituting 6 for 'r' you get [tex]\pi 6^{2}[/tex].

According to PEMDAS, you have to solve 6 to the power of 2 first. 6 to the power of 2 is 36.

So the area of the circle is [tex]36\pi[/tex] inches squared.

If you would like to completely solve for the area, you can multiply 36 by 3.14. 36 times 3.14 equals 113.04. Note that this is not the exact answer, because [tex]\pi[/tex] is a never ending number, meaning if you multiplied both numbers, you product would also be a never ending number.

So the area of the circle is [tex]36\pi[/tex] or about [tex]113.04[/tex] inches squared.

A turntable has a diameter of 40 cm what its circumference

Answers

Answer:

Circumference of turntable is 125.6 cm

Step-by-step explanation:

Diameter of turntable = 40 cm

We need to find circumference of turntable.

The formula used to calculate circumference is: [tex]Circumference=2\pi r[/tex]

where r is radius

We know that: [tex]radius=\frac{diameter}{2}[/tex]

Finding radius first:

[tex]radius=\frac{diameter}{2}\\radius=\frac{40}{2}\\radius = 20 \ cm[/tex]

So, radius r=20 cm

Now finding circumference

[tex]Circumference=2\pi r\\Circumference=2\times3.14\times20\\Circumference=125.6 \ cm[/tex]

So, circumference of turntable is 125.6 cm

point k lies at (-3,4) Image

Answers

Answer:

[tex]k(x,y) --> k'(x,y-7)[/tex]

Step-by-step explanation:

Given

[tex]k = (-3,4)[/tex]

Translation: 7 units down

Required

Determine the rule to produce k'

When an (x,y) coordinate is translated down by h units, the resulting point is:

(x,y) --> (x, y - h)

In this case:

[tex]h = 7[/tex]

So, we have:

[tex]k(x,y) --> k'(x,y-7)[/tex]

Hence, option A answers the question.

Solving further to determine the coordinates of k'.

[tex]k = (-3,4)[/tex]

[tex]k' = (-3,4-7)[/tex]

[tex]k' = (-3,-3)[/tex]

Solve x2 - 16 = 59. What does x
equal?

Answers

Answer:

37.5

Step-by-step explanation:

Answer:  x = 75/2 = 37.5

Step by Step:

Solve for x:

2 x - 16 = 59

Hint: | Isolate terms with x to the left hand side.

Add 16 to both sides:

2 x + (16 - 16) = 16 + 59

Hint: | Look for the difference of two identical terms.

16 - 16 = 0:

2 x = 59 + 16

Hint: | Evaluate 59 + 16.

59 + 16 = 75:

2 x = 75

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 75 by 2:

(2 x)/2 = 75/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

Answer:  x = 75/2 = 37.5

I don't understand this question, help me, someone, please

Answer:

Arranging the terms from least to greatest:

[tex]\frac{3039}{1000}<\frac{3200}{1000}<\frac{3990}{1000}<\frac{8200}{1000}[/tex]

Now actual terms arranged from least to greatest will be:

[tex]3\frac{39}{1000}<3\frac{1}{5} <3\frac{99}{100}<3\frac{52}{10}[/tex]

Step-by-step explanation:

We need to arrange the weights [tex]3\frac{1}{5} ,3\frac{39}{1000},3\frac{99}{100},3\frac{52}{10}[/tex] from least to greatest.

To arrange them in least to greatest we need to convert them into improper fractions and then make their denominators same.

[tex]3\frac{1}{5}=\frac{16}{5} \\3\frac{39}{1000}=\frac{3039}{1000} \\3\frac{99}{100}=\frac{399}{100} \\3\frac{52}{10}=\frac{82}{10}[/tex]

Now, Making their denominator same by taking LCM of 5,1000,100 and 10

The LCM is 1000

Now the fractions will become:

[tex]\frac{16}{5}=\frac{16*200}{5*200}=\frac{3200}{1000}[/tex]

[tex]\frac{399}{100}=\frac{399*10}{100*10}=\frac{3990}{1000}[/tex]

[tex]\frac{82}{10}=\frac{82*100}{10*100}=\frac{8200}{1000}[/tex]

Now we have fractions: [tex]\frac{3200}{1000},\frac{3990}{1000},\frac{8200}{1000},\frac{3039}{1000}[/tex]

Now the smallest term will be one having smallest numerator

Arranging the terms from least to greatest:

[tex]\frac{3039}{1000}<\frac{3200}{1000}<\frac{3990}{1000}<\frac{8200}{1000}[/tex]

Now actual terms arranged from least to greatest will be:

[tex]3\frac{39}{1000}<3\frac{1}{5} <3\frac{99}{100}<3\frac{52}{10}[/tex]
