The solution for pi is π = 2A/r² where r is the radius.

The area of a circle is defined as the space occupied by the circle in a two-dimensional plane. In other word, the space occupied under the region or circumference of a circle is called the area of the circle.

The formula for the area of a circle is A = πr²,

Where r is the radius of the circle.

For example, if the radius of circle is 6cm, then its area will be: Area of a circle with 6 cm radius = πr² = π(6)² = 36π square cm.

Given data as :

A = 1/2 πr²

Solve for pi

⇒ A = 1/2 πr²

Multiply by 2 both the side

⇒ 2A =  πr²

⇒ 2A/r² =  π  or

⇒  π = 2A/r²

If A = 76 cm² and π  = 22/7,

⇒ A = πr²

⇒ A/π = r²

⇒ √A/π = r

Substitute the values, we have:

⇒ √76 /(22/7) = r

⇒ √76 * 7/22 = r

⇒ √532/22 = r

⇒ √24.1818 = r

⇒ 4.917 = r

⇒ r = 4.92 cm (Rounding to two decimal places)

Answer:

Part A)

Height = 19.3 feet

Part B)

Distance = 5.2 feet

Step-by-step explanation:

Part A)

Let ladder reaches upto the h height of the wall.

[tex] \therefore \sin \theta =\frac{h}{length\: of\: the \:ladder} [/tex]

[tex] \therefore \sin 75\degree =\frac{h}{20} [/tex]

[tex] \therefore 0.9659258263 =\frac{h}{20} [/tex]

[tex] \therefore 0.9659258263\times 20 = h [/tex]

[tex] \therefore 19.3185165 \: ft= h [/tex]

[tex] \therefore h = 19.3 \: ft= h [/tex]

Part B)

Let the distance from the wall to the base of the ladder be x feet.

[tex] \therefore \cos \theta =\frac{x}{length\: of\: the \:ladder} [/tex]

[tex] \therefore \cos 75\degree =\frac{x}{20} [/tex]

[tex] \therefore 0.2588190451 =\frac{x}{20} [/tex]

[tex] \therefore 0.2588190451\times 20 = x [/tex]

[tex] \therefore 5.1763809 \: ft= x [/tex]

[tex] \therefore x = 5.2 \: ft [/tex]

______________________________

 - We do this first because we need the get rid of the parenthesis in order to solve this like a regular problem. In this case the only way to do so was to divide by 2 to separate the Number/Variable from the parenthesis.

Equation at the end of Step 1:

 - We do this because we can't have 2 variables at the end of the equation so it's best to just combine them.

Equation at the end of Step 2:

 - We divided for the last step since their was 1 variable connected by a number and another number on the opposite side of the equal.

Answer:

Number of extra boxes= 120

Step-by-step explanation:

Giving the following information:

Batteries per box= 50

Number of batteries= 18,000

Number of batteries in ecxess= 6,000

We need to calculate the number of boxes required to cover the 6,000 extra batteries:

Number of extra boxes= number of batteries / batteries per box

Number of extra boxes= 6,000 / 50

Number of extra boxes= 120

The answer is 6+(-4) = 2

Answer:  240 liters

=======================================================

Work Shown:

x = capacity of barrel in liters

This value of x is some positive real number. It represents the most amount of water the barrel can hold.

The problem states that the barrel is 2/3 full to start with. This means, we start off with (2/3)x liters of water. Then we subtract off 60 of them to get to 5/12 full, meaning we have (5/12)x liters left.

We can form this equation

(2/3)x - 60 = (5/12)x

Multiply both sides by 12 to clear out the fractions

(2/3)x - 60 = (5/12)x

12*( (2/3)x - 60 ) = 12*(5/12)x

12*(2/3)x - 12*60 = 12*(5/12)x

8x - 720 = 5x

From here we solve for x

8x - 5x = 720

3x = 720

x = 720/3

x = 240

The barrel's full capacity is 240 liters

--------------------------

Check:

2/3 of 240 = (2/3)*240 = 160

The barrel starts off with 160 liters of water inside.

We then use 60 of them to be left with 160-60 = 100 liters

Note how 100/240 = (5*20)/(12*20) = 5/12, showing that 100 liters out of 240 total reduces to the fraction 5/12. In other words, when we say "5/12 full" we mean 100 liters full. This helps confirm we have the right answer.

Answer:

  B, E

Step-by-step explanation:

The ratios of side lengths in a 30-60-90 triangle are ...

  1 : √3 : 2

The two legs are the shorter sides, so any ratio that reduces to 1 : √3 is an appropriate choice:

  B.  1 : √3

  E.  2√3 : 6

Answer:

To solve the system below by substitution, replace y in the second equation with 7−6x.

==> False

This statement is false. To solve the system by substitution, replace x in the second equation with 7−6x.

==> False.

This statement is false. To solve the system by substitution, replace y in the first equation with 7−6x.

==> False

This statement is false. To solve the system by substitution, replace y in the second equation with 6x−7.

==> True.

From the first equation, 6x-y=7

y= 6x-7

Answer: This statement is false. To solve the system by​ substitution, replace y in the second equation with 6x−7.

Answer:

-6 is the missing value.....

Answer:

(-6, 8); the missing value is -6

Step-by-step explanation:

First, you need to solve the given equation for x

1: 2x + 3y = 12 (Given)

2: 2x = -3y + 12 (Subtract 3y from both sides to isolate x)

3: x = -1.5y + 6 (Divide both sides by 2)

Now, you can solve for the missing x in the solution set (x, 8):

where x = -1.5y + 6 and y = 8,

x = -1.5(8) + 6

x = -12 + 6

x = -6

So, the missing value is -6
