can someone please help me find the area of a regular pentagon of radius 4m? thank you :(
Answer:38.07
Step-by-step explanation:
If you don't have the apothem value, you will need more information to find the area accurately. The radius alone does not provide enough information to find the area of the regular pentagon.
To find the area of a regular pentagon with a given radius, we need to know the apothem (the distance from the center of the pentagon to the midpoint of one of its sides) in addition to the radius. However, you mentioned only the radius, and it is not sufficient to directly find the area.
If you have the apothem value, you can use the following formula to calculate the area of a regular pentagon:
Area = (5/4) * apothem * side length

What is the value of Q3 of the data represented by the box plot?
Enter your answer in the box.
Answer:
Q3 = 30
Step-by-step explanation:
minimum value = 5
Q1 = 20 (this is the median of the lower half of data)
Median (sometimes called Q2) = 25
Q3 = 30 (this is the median of the upper half of data)
maximum value = 45
The inequality x < 15 can be used to represent how tall a tree is, where x is it’s height in feet. Which of these statements best describes how tall the tree is

Step-by-step explanation:
1st question is 4-- count the points that fall above the line
2nd question is 2 out of 8, or 1 out of 4
there are only 2 players who played at least 17 matches AND scored about 5000. There are 8 players who played at LEAST 17 matches
Answers:
1. 4
2. ¼
Explanations:
1. the question is asking how many players were awarded more points than the prediction of the line of best fit (trend line), which can be translated to how many dots are above the line on the graph. 4 dots can be counted above the line
2. 8 players played at least 17 tournaments. of these 8 players, only 2 scored more than 5000 ranking points.
thus, to find the probability, we take 2 ÷ 8 = ¼

Total marks: 4
Answer:
52°
Step-by-step explanation:
180-112=68
120-68=52
The size of the angle marked x is 52°.
Given that a hexagon and parallelogram share the same one vertex and the angle of the parallelogram is 112°
To determine the size of the angle marked x by utilizing the properties of a regular hexagon and the given angle of 112°.
A regular hexagon has interior angles measuring 120° each. Since the hexagon is regular, all six interior angles are congruent. We can divide the hexagon into six equal triangles, each having an angle of 120°.
In parallelogram, the opposite angles are congruent and the sum of adjacent angles is 180°.
The parallelogram adjacent to the hexagon shares the same vertex as the hexagon's interior angle.
Let the angle adjacent to 112° in parallelogram be a and a is adjacent to angle x in hexagon,
By using parallelogram property gives,
a + 112° = 180°
Subtract 112° from both the sides, gives,
a = 68°
x and a form one angle of the hexagon which is equal to 120° gives,
x + a = 120°
Substitute the value of a = 68° in the above equation
x+ 68° = 120°
Subtract 68° from both the sides, gives,
x = 52°
Hence, the size of the angle marked x is 52°.

Find the measure of the exterior angle.
Answer:
Option (C)
Step-by-step explanation:
By the property of an exterior angle,
Exterior angle of a triangle is equal to the sum of two opposite interior angles.
(15x + 34)° = 29° + (12x + 26)°
15x + 34 = 29 + 12x + 26
15x - 12x = 55 - 34
3x = 21
x = 7
Measure of exterior angle = (15x + 34)°
= 15(7) + 34
= 105 + 34
= 139°
Option (C) is the answer.

557.8m²Step-by-step explanation:
2 opposite semicircle are same
diameter = 9m
radius = 4.5m --- (diameter = 1/2radius)
area of semicircle = 1/2 × π × radius²
= 1/2 × 3.14 × 4.5×4.5
= 31.79m²
2 semicircles area = 31.79 × 2
= 63.8m²
______________________________
______________________________
other 2 opposite semicircle are same
diameter = 20m
radius = 10m --- (diameter = 1/2radius)
area of semicircle = 1/2 × π × radius²
= 1/2 × 3.14 × 10×10
= 157m²
2 semicircles area = 157 × 2
= 314m²

______________________________
length = 20m ----- ( given )
breadth = 9m ----- ( given )
area = length × breadth
