A circle has a diameter of
16". (4 pts.)
What is the approximate
Circumference?
What is the approximate area?
Show ur work 40 points!!

Answer and explanation:

Take the area formula:

A = L * W

Then manipulate it to fit the context of which unknown you are finding:

Problem 1

[tex]\dfrac{36 = 4 * W}{4}[/tex]

[tex]9 = W[/tex]

So, the length of side c is 9 mm.

Problem 2

[tex]\dfrac{21 = W * 21}{21}[/tex]

[tex]1 = W[/tex]

So, the length of side a is 1 m.

Problem 3

[tex]\dfrac{49 = 7 * W}{7}[/tex]

[tex]7=W[/tex]

So, the length of side t is 7 cm.

Step-by-step explanation:

[tex]area = l \times b[/tex]

[tex]area = \frac{3}{7} \times \frac{2}{9} [/tex]

[tex]area = \frac{6}{64} [/tex]

[tex]area = 0.09375units ^{2} [/tex]

The volume of a silo cylinder with radius of 8 feet and height of 36 feet is 7235 feet cube.

The volume of a cylinder can be calculated as follows;

Volume = πr²h

where

Therefore,

r = 8 ft

h = 36 ft

volume = 3.14 × 8² × 36

volume = 3.14 × 64 × 36

volume of the silo = 7234.56

Therefore, the volume of the cylindrical silo is 7235 ft³

Answer:

y = -2

Step-by-step explanation:

y - y₁ = m (x - x₁)

y + 2 = 0 (x + 4)

y + 2 = 0

Final simplified equation: y = -2

Hope this helps!

The required y-intercept is (0, 7), and the horizontal asymptote y = 2. Option A is correct.

It is to detrmine the y-intercept and the horizontal asymptote of g(x) = 2x + 7.

A line can be defined as it is the shortest distance between two points on the graph called a line. Equation of the y = mx + c, where c is the y-intercept and m is the slope of the line.

The y-intercept of g(x) = 2x + 7 is the y-coordinate of a point where a line, curve, or surface intersects the y-axis i.e. (0, 7).

An asymptote of g(x) = 2x + 7 is a line that a graph approaches without touching i.e. y = 2.

Thus, The required y-intercept is (0, 7), and the horizontal asymptote y = 2. Option A is correct.

Answer: 15 ft

Step-by-step explanation:

You basically add all the sides:

3 + 3 + 3 + 3 +3 = 15 ft

And if you have to add 12 ft then the answer should be 27 ft in total.

1.6667

Step-by-step explanation:

the lengths are the same on both sides which makes the triangles equilateral

therefore the scale=5/3

=1.6667

Answer: Well, the answer really depends. But here are a few ways you can figure this out.

Step-by-step explanation:

If the two lines intersect once, then they have one solution.

If they intersect twice there are two solutions

If the lines never intersect, there are no solutions

And if the lines are identical, meaning that their equation is exactly the same. There are infinite solutions.

A solution with systems of equations is determined by the point of intersection. Your answer is the point of intersection

Answer:

no s

Step-by-step explanation:

Applying the definitions of angles on a straight line and vertical angles, the missing angle measurementts are given in the table atached below.

Angles found on a straight line equals 180 degrees.

Vertical angles are congruent angles that lie directly opposite each other.

Second Row:

m∠LGK = 45° (given in the diagram)

m∠IGH = 35° (given in the table)

m∠KGJ = m∠IGH (vertical angles)

m∠KGJ = 35°

m∠JGI = 180 - m∠KGJ (angles on a straight line)

m∠JGI = 180 - 35 = 145°

m∠HGL = 180 - m∠LGK - m∠IGH (angles on a straight line)

m∠HGL = 180 - 45 - 35 = 100°

Third Row:

m∠LGK = 45° (given in the diagram)

m∠HGL = 97° (given in the table)

m∠KGJ = 180 - m∠HGL - m∠LGK (angles on a straight line)

m∠KGL= 180 - 97 - 45 = 38°

m∠JGI = 180 - m∠KGJ (angles on a straight line)

m∠JGI = 180 - 38 = 142°

m∠IGH = m∠KGL (vertical angles)

m∠IGH = 38°

Thus, applying the definitions of angles on a straight line and vertical angles, the missing angle measurementts are given in the table atached below.

Empirical probability

Step-by-step explanation:

Empirical probability is data collected from experiment and real-life situation.

The "empirical probability" of an outcome is obtained by dividing the frequency of occurrence of an event by the number of trails of the experiment.

Answer:

x = 81

Step-by-step explanation:

Given:

[tex]\displaystyle \large{19x+28=20x-53}[/tex]

Subtract both sides by 28:

[tex]\displaystyle \large{19x+28-28=20x-53-28}\\\displaystyle \large{19x=20x-81}[/tex]

Subtract both sides by 19x:

[tex]\displaystyle \large{19x-19x=20x-81-19x}\\\displaystyle \large{0=x-81}[/tex]

Add both sides by 81:

[tex]\displaystyle \large{0+81=x-81+81}\\\displaystyle \large{81=x}\\\displaystyle \large{\therefore x=81}[/tex]

Therefore, the solution is x = 81
