The area of a circle as a function of the circumference when calculated from substituting values in their formulas gives the expression written as; A = πC²/4

The formula for area of a circle is;

A = πr²

Making area as a function of the radius will give;

r = √(A/π)

Formula for Circumference of a Circle is;

C = 2πr

Thus making Circumference as a function of the radius will give;

r = C/2

Putting C/2 for r in the area formula gives;

A = π(C/2)²

A = πC²/4

The approximate diameter of this circle is equal to 11.0 in.

Given the following data:

To determine the approximate diameter of this circle:

Mathematically, the circumference of a circle is given by the formula:

[tex]Circumference = \pi D[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]35\frac{13}{21}=\frac{22}{7} D\\\\\frac{748}{21} =\frac{22D}{7} \\\\748\times 7=22D \times 21\\\\5236=462D\\\\D=\frac{5236}{462}[/tex]

Answer:

x = 12

Step-by-step explanation:

9(x-11) = 9

divide by 9 by 9         x-11 = 1

add 11 to 1      x= 12

Pretty much you take a value on the left and do the opposite of what its doing and then do it to the number on the right. since 9 was going to multiply on the left, then you would divide it on the right

Answer:

x = 1

y = 9

Step-by-step explanation:

x + 7y = 64

x + 3y = 28

4y = 36

y = 9

x + 7(9) = 64

x + 63 = 64

x = 1

Hey there!

6s + 21 > 63

SUBTRACT 21 to BOTH SIDES

6s + 21 - 21 > 63 - 21

CANCEL out: 21 - 21 because it give you 0

KEEP: 63 - 21 because it help compare to the s-value.

NEW EQUATION: 6s > 63 - 21

SIMPLIFY IT!

6s > 42

DIVIDE 6 to BOTH SIDES

6s/6 > 42/6

CANCEL out: 6/6 because it give you 1

KEEP: 42/6 because it help compare to the s-value
NEW EQUATION: s > 42/6

SIMPLIFY IT!

s > 7

Therefore, your answer is: s > 7

Answer:

2

Step-by-step explanation:

Linear equation form:  y = mx + b

(where m is the slope and b is the y-intercept)

The rate of change for a line is the slope.

Function 1:  y = 6

⇒ the slope is zero so the rate of change is zero

Function 2:  y = 2x + 7

⇒ the slope is 2 so the rate of change is 2

Therefore, 2 - 0 = 2

So the rate of change of function 2 is 2 more than the rate of change of function 1

Answer:

2(1/2)

Step-by-step explanation:

1(2/3) = 5/3

5/3 divided into 2/3

is the same as

5/3 multiplied by 3/2

        5/3 x 3/2 = 15/6  

15/6 = 5/2

5/2 = 2(1/2)

Answer:

150

Step-by-step explanation:

So I will shorten Eric, and Bob's names as E, and B.

So the equations are this

B-E = B+E - 240, E as Eric, and B as Bob, and this E+B=9(E-B)

Move the variables and you get

-2E =- 240

Just divide them both by -2

and E=120

So when we know the value of E we can just plug it into the 1st question

120+B=9B+1080

Moves the Variables and numbers to the other side

8B=1200

1200/8= 150

B=150

There is Bob's weight

Answer:

1,005.3 cm

Step-by-step explanation:

The radius: r = diameter/2 = 80/2 = 40 mm = 4 cm. The height: h = 20 cm. Conclusion: The volume is 1,005.3 cubic cm (approximately)

The circulation of V around the given path (call it C) is simply the line integral of V along C. Since C is a closed curve, we can use Green's theorem.

[tex]\displaystyle \int_C \vec V(x,y) \cdot d\vec r = \iint_{\mathrm{int}(C)} \frac{\partial}{\partial x}\left[\frac{x+1}{(x+1)^2+4y^2}\right] - \frac{\partial}{\partial y}\left[-\frac{y}{(x+1)^2+4y^2}\right] \, dx\,dy[/tex]

where int(C) is the interior or region bounded by C.

We have

[tex]\dfrac{\partial}{\partial x}\left[\dfrac{x+1}{(x+1)^2+4y^2}\right] = \dfrac{4y^2 - (x+1)^2}{((x+1)^2+4y^2)^2}[/tex]

[tex]\dfrac{\partial}{\partial y}\left[-\dfrac{y}{(x+1)^2+4y^2}\right] = \dfrac{4y^2-(x+1)^2}{((x+1)^2+4y^2)^2}[/tex]

so the double integral and hence the circulation is zero.
