Find the circumference in inches

Mathematics
2 answers:
artcher [175]2 years ago

Answer:

87.92 in.

Step-by-step explanation:

The formula for circumference of a circle is: πd (diameter) or 2πr(radius).

π - pi

Here, only the radius (14) is shown. So we would have to use this formula: 2πr.

Now, let's just plug-in the numbers.

**3.14 is commonly used for pi.**

2πr

2 × 3.14 × 14 = 87.92

OR

We could simply double the radius, and use this formula instead: πd

πd

3.14 x 28 = 87.92

As you can see, I got the same answer either way.

Therefore, the circumference of this circle is 87.92 in.

Find the measure of each angle indicated.​
Brilliant_brown [7]

Answer:

90 degrees

Step-by-step explanation:

Sum of the angles in a triangle = 180°

Opposite angles are equal

For two parallel lines and a transversal,

corresponding angles are equal, and

alternate angles are equal.

45+45=90.

180-90=90

Plus, you can see that the angle forms a perfect 90 degree angle.

Find the length of the height of the right trapezoid shown below, if it has the greatest possible area and its perimeter is equa
Artyom0805 [142]

Answer:

The height of the right trapezoid is   \frac{6}{5+\sqrt{3}}\ units

Step-by-step explanation:

Let

x ----> the height of the right trapezoid in units

we know that

The perimeter of the figure is equal to

P=AB+BC+CD+DH+HA

we have

P=6\ units

AB=BC=CH=HA=x ---> because is a square

substitute

6=x+x+CD+DH+x

6=3x+CD+DH -----> equation A

<em>In the right triangle CDH</em>

sin(30\°)=\frac{CH}{CD}

sin(30\°)=\frac{1}{2}

so

Remember  that CH=x

\frac{1}{2}=\frac{x}{CD}

CD=2x

tan(30\°)=\frac{CH}{DH}

tan(30\°)=\frac{\sqrt{3}}{3}

so

\frac{\sqrt{3}}{3}=\frac{x}{DH}

DH=x\sqrt{3}

substitute the values in the equation A

6=3x+CD+DH -----> equation A

CD=2x

DH=x\sqrt{3}

6=3x+2x+x\sqrt{3}

6=5x+x\sqrt{3}

6=x[5+\sqrt{3}]

x=\frac{6}{5+\sqrt{3}}\ units

1.If a line with a slope of -3 crosses the y-axis at (0,7), what is the equation of the line?
gogolik [260]

y = mx + b    "m" is the slope, "b" is the y-intercept (the y value when x = 0)


1. slope: -3

y-intercept: 7

y = -3x + 7

Your answer is B

y + 3x = 7   Subtract 3x on both sides

y = -3x + 7


2. y + 9(x + 3) = 0     Multiply/distribute 9 into (x + 3)

y + 9x + 27 = 0      Subtract 9x and 27 on both sides to get "y" by itself

y = -9x - 27

slope: -9

y-intercept: -27 or (0,-27)

Your answer is D


3. Point-slope form:   y - y₁ = m(x - x₁)

slope: -11

(x₁ , y₁) = (-5, 7)


y - 7 = -11(x - (-5))  The two negative signs becomes a positive

y - 7 = -11(x + 5)

Your answer is C


4. For this question, I think you get it from point-slope form to slope-intercept form (I'm not sure, but you still get the same answer if you just do slope-intercept form)

slope: -4

(x₁ , y₁) = (2, -8)


y - y₁ = m(x - x₁)

y - (-8) = -4(x - 2)

y + 8 = -4(x - 2)     Multiply/distribute -4 into (x - 2)

y + 8 = -4x + 8       Subtract 8 on both sides to get "y" by itself

y = -4x

Your answer is A
