A regular pentagon has an apothem of 4 centimeters.
What is the area of the regular pentagon in square centimeters? Round your answer to
the nearest tenth.
Answers
Answer:
[tex] \boxed{A ≈ 58.1 \: cm^{2}} [/tex]
Step-by-step explanation:
When given a regular polygon.
s = a × 2 tan (π / n [radians]).
s = a × 2 tan (180 / n [degrees])
A = (n × s × a) / 2
Where s is the side length, n is the number of sides, a is the apothem length, and A is the area.
You may also see A = p × a.
Where p is the perimeter, the perimeter is the same as n × s.
The apothem is also known as the inradius.
______________________________________
Given a regular pentagon which has 5 sides, and an apothem of 4 cm.
s = 4 × 2 tan (180 / 5) = 4 × 2 × (0.726542528) = 8 × (0.726542528) = 5.81234022404.. ≈ 5.8 cm.
Now that we have sufficient information, we can now solve for the area.
A = (n × s × a) / 2
A = (5 × 5.81234022404.. cm × 4) / 2
A = (20 × 5.81234022404.. cm) / 2
A = (116.236804481.. cm²) / 2
A = 58.1234022404.. cm²
A ≈ 58.1 cm²
The area of the regular polygon is the amount of space it covers
The area of the regular polygon is 58.1 square centimeter
The given parameter is:
[tex]\mathbf{a=4}[/tex]
Start by calculating the side lengths using
[tex]\mathbf{s = 2a\ tan (\frac{180}{ n} )}[/tex]
Where n represents the number of sides.
In this case
[tex]\mathbf{n =5}[/tex]
So, we have:
[tex]\mathbf{s = 2a\ tan (\frac{180}{ 5} )}[/tex]
[tex]\mathbf{s = 2a\ tan (36)}[/tex]
Substitute 4 for (a)
[tex]\mathbf{s = 2 \times 4\ tan (36)}[/tex]
[tex]\mathbf{s = 8\ tan (36)}[/tex]
[tex]\mathbf{s = 5.8123}[/tex]
The surface area is then calculated as:
[tex]\mathbf{A = \frac{n \times s \times a}{ 2}}[/tex]
So, we have:
[tex]\mathbf{A = \frac{5 \times 5.8123 \times 4}{2}}[/tex]
[tex]\mathbf{A = 58.123}[/tex]
Approximate
[tex]\mathbf{A = 58.1}[/tex]
Hence, the area of the regular polygon is 58.1 square centimeter

A freight train and a passenger train leave a rail yard at the same time and travel on parallel tracks,
The passenger train travels 5 mph faster than the freight train. The combined distance traveled
after 3 hours is 135 miles. What is the average speed of the freight train?
A 70 mph
B 20 mph
C 22 mph
D 19 mph
Answers
Answer:
C. 22 mph
Step-by-step explanation
Assign the speed of the freight train as; x mph
Since the passenger train travels 6 mph faster than the freight train, its speed will be; (x + 6) mph
In 2 hours, the freight and passenger trains will have traveled (distance = speed * time);
2x and 2(x + 6) miles respectively
Both add up to 100 miles. Therefore;
2x + 2(x +6) = 100
4x + 12 = 100
4x = 88
x = 22
x + 6 = 28

If p+q has a value of 12/5, and has a value of 4/5, what is the value of q? A. 5/8 B. 8/5 C. 1/3 D. 3/2 step-by-step
Answers
Answer:
Option B
Step-by-step explanation:
It's given that p + q has a value of [tex]\frac{12}{5}[/tex]
So the equation representing the relation will be,
p + q = [tex]\frac{12}{5}[/tex] --------(1)
Value of p is [tex]\frac{4}{5}[/tex]
p = [tex]\frac{4}{5}[/tex]
By substituting the value of p in the equation (1),
[tex]\frac{4}{5}+q=\frac{12}{5}[/tex]
q = [tex]\frac{12}{5}-\frac{4}{5}[/tex]
q = [tex]\frac{8}{5}[/tex]
Therefore, Option B will be the correct option.

Angle A is 180 minus the two other angles since angle totals = 180.
