Area of a circle:

[tex]\pi * r^2[/tex]

Diameter is twice the radius, so the radius is 20 ft.

Thus the area of grass is 400pi

Answer:

The answer is D

Step-by-step explanation:

You are basically looking for the area of this circle, the formula would be A=Pi*r^2. So plug the values in and it would be, A=3.14*400, we know the radius is 20 because the diameter is double that, and square the radius, this gives you 400.

25

Step-by-step explanation:

Find the volume of both boxes

V = base * height

Bigger box

base = 50 * 30 = 1500

1500 * 20 = 30,000

Smaller box

b= 10 * 30 = 300

300 * 4 = 1200

30,000 / 1200= 25

Answer:

Travis should pick to play the hat game.

Step-by-step explanation:

You would need to evaluate the probablity of winning in each option

Option 1 (rolling die)

p(roll 2 or 3)=2/6

p(roll 2 or 3)=1/3=.33

Option 2 (pick letters)

p(pick A or B) = 2/5

p(pick A or B) = .4

.33<.4

Since option 2 with picking letters has a higher chance of winning, then Travis should play the second game to win the goldfish as a higher chance of winning makes it easier for him to win the prize.

Answer:

Step-by-step explanation:

Let width = x

Length = 7 + x

Perimeter = 42 yards

2*(length + width) = 42

2* ( 7 + x + x) = 42

7 + 2x = 42/2

7 + 2x = 21

2x = 21 - 7

2x = 14

x = 14/2

x = 7

Width = 7 yards

Length = 7 + 7 = 14 yards

Answer:

B. Add the area of the rectangle with the area of the triangle.

Step-by-step explanation:

Simple Answer..

The possible areas to find the area of the composite figure is; Add the area of the rectangle with the area of the triangle and Multiply the area of the rectangle by 2.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

The composite figure is made up of two shapesas; a rectangle and a triangle. To determine the total area of the composite figure, we can use one of the methods:

First Add the area of the rectangle with the area of the triangle:

We can find the area of the rectangle by multiplying its length and width. We can determine the area of the triangle by multiplying its base and height and then dividing by 2.

Once we get both areas, we can add them together to find the total area of the composite figure.

Multiply the area of the rectangle by 2:

Since the composite figure consists of two rectangles, we can determine the area of one rectangle and then multiply it by 2 to get the total area of the composite figure.

Therefore, by area, the answer will be x2 area of the rectangle and sum of the area of the rectangle and triangle.

The number that satisfies both conditions (-5+z being positive and -6+z being negative) given in the question is z = 6.

To solve this problem, we use the clues given in the question that (-5+z) is positive and (-6+z) is negative. A number, when added to -5, resulting in a positive one, must be greater than 5. However, when the same number is added to -6, it results in a negative answer, meaning it must be less than 6.

Considering both conditions and finding a number that meets them, we can see that z = 6 is the only possible option. This is because 6 is greater than 5 making -5+6 positive. However, since 6 is equal to 6, -6+6 equals zero, and zero isn’t considered negative, thus satisfying both conditions.

Answer:The answer is 10r-84=4

Step-by-step explanation:

1.Perimeter: [tex]\( P ≈ 31.05 \, mm \)[/tex]

2. Apothem: [tex]\( a ≈ 4.89 \, mm \)[/tex]

3. Area: [tex]\( Area ≈ 75.91 \, mm^2 \)[/tex]

So, the area of the regular 15-gon with a radius of 5 mm is approximately [tex]\( 75.91 \, mm^2 \).[/tex]

To find the area of a regular polygon, you can use the formula:

[tex]\[ Area = \frac{1}{2} \times Perimeter \times Apothem \][/tex]

Where:

- Perimeter is the total length of all the sides of the polygon.

- Apothem is the distance from the center of the polygon to the midpoint of any side.

For a regular polygon, the apothem can be calculated using trigonometry. In this case, the regular 15-gon (also called a pentadecagon) has 15 equal sides.

Let's break down the steps:

1. Calculate the Perimeter:

  The perimeter of a regular polygon with ( n ) sides can be calculated as [tex]\( P = n \times s \)[/tex], where ( s ) is the length of each side. Since we're given the radius of the polygon, we need to calculate the length of one side using trigonometry.

2. Calculate the Apothem:

  The apothem of a regular polygon can be calculated using the formula:

[tex]\[ a = r \times \cos\left(\frac{\pi}{n}\right) \][/tex]

  where ( r ) is the radius of the polygon, and ( n ) is the number of sides.

3. Plug the values into the Area Formula:

  Once you have both the perimeter and the apothem, you can plug them into the area formula and calculate the area.

Let's do the calculations:

1. Calculate the Perimeter:

  The length of one side ( s )) can be calculated using trigonometry. Since we're dealing with a 15-gon, each interior angle is[tex]\( \frac{(15-2) \times 180°}{15} = 156° \).[/tex]

  Using the law of cosines:

[tex]\[ s = 2 \times r \times \sin\left(\frac{180°}{15}\right) \][/tex]

[tex]\[ s = 2 \times 5 \times \sin(12°) \][/tex]

 [tex]\[ s ≈ 2 \times 5 \times 0.207 ≈ 2.07 \, mm \][/tex]

  So, the perimeter (( P )) is:

[tex]\[ P = 15 \times 2.07 ≈ 31.05 \, mm \][/tex]

2. Calculate the Apothem:

[tex]\[ a = 5 \times \cos\left(\frac{\pi}{15}\right) \][/tex]

 [tex]\[ a = 5 \times \cos(12°) \][/tex][tex]\[ a = 5 \times \cos\left(\frac{\pi}{15}\right) \][/tex]

[tex]\[ a ≈ 5 \times 0.978 ≈ 4.89 \, mm \][/tex]

3. Plug the values into the Area Formula:

[tex]\[ Area = \frac{1}{2} \times 31.05 \times 4.89 \][/tex]

[tex]\[ Area ≈ \frac{1}{2} \times 31.05 \times 4.89 ≈ 75.91 \, mm^2 \][/tex]

So, the area of the regular 15-gon with a radius of 5 mm is approximately [tex]\( 75.91 \, mm^2 \)[/tex].

The solution to the system of linear equations graphed below if, On a coordinate plane, 2 lines intersect at (3.5, negative 4) is (0, negative 4).

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line. Functions like y = mx, where m can be any constant, are considered linear equations.

Given:

On a coordinate plane, 2 lines intersect at (3.5, negative 4),

the coordinates of the intersection point are (3.5, -4)

The equation of must satisfy these coordinates,

On the y-axis line will have no x-intercept i.e. x = 0

Hence, the coordinates will become (0, -4)

Thus, the solution to the system of linear equations graphed below is (0, negative 4).
