A cylinder has a diameter of 40 feet and a height of 32 feet. What is the surface area of the cylinder? Express the answer in terms of Pi. Recall the formula S A = 2 pi r squared + 2 pi r h. 1,320 pi feet squared 1,792 pi feet squared 2,080 pi feet squared 2,640 pi feet squared
Answers
Answer:
2080
Step-by-step explanation:
The surface area of the cylinder is 2080π square feet. Answer: 2,080 pi feet squared.
What is a cylinder?A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.
The formula for the surface area of a cylinder is:
SA = 2πr² + 2πrh
where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is the mathematical constant pi (approximately equal to 3.14159).
Since the diameter is given as 40 feet, the radius is half of that, or 20 feet.
So, substituting the values into the formula, we get:
SA = 2π(20)² + 2π(20)(32)
SA = 2π(400) + 2π(640)
SA = 800π + 1280π
SA = 2080π
Therefore, SA = 2080π.

A rectangular garden has a walkway around it. Find the area of the walkway.
Answers
Answer:
Step-by-step explanation:
Im no expert but you would need information on the length and width of the rectangular garden and walkway. To figure this out you would need the information on the width of the walkway and length and width of the rectangle.
Let's pretend a rectangle has a width of 4 and length of 6. I would do 4x6. Then for the walkway lets pretend the width is 3. Since the we know the length of the rectangle is 6 and the width 4, I would do 2(6x3)+2(4x3).

In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.
\(\huge{\mathfrak{\colorbox{black}{\textcolor{lime}{I\:hope\:this\:helps\:!\:\:}}}}\)

Minimum value: 18
First quartile (Q1): 22
Median: 29
Third quartile (Q3): 36
Maximum value: 38
The box plot is created using these values. A box is drawn from Q1 to Q3 with a line inside the box at the median. Whiskers are drawn from the box to the minimum and maximum values. Any data points beyond the whiskers are plotted as individual points.
In this box plot, the data is dispersed fairly evenly, with no outliers beyond the whiskers. The box is centered around the median, indicating that the data is roughly symmetric. The lower half of the data is slightly more spread out than the upper half, as indicated by the longer whisker on the left side of the box. Overall, the box plot shows that the data is relatively consistent, with no extreme values.

what is the measure of each angle in a pentagon if the lengths of all five sides are equal? A-180 B-120 C-108 D-60
Answers
C (108)
Step-by-step explanation:
Angles in a pentagon must add up to 540 degrees.
All sides equal mean all angles are equal
so all you must do is divide 540 by 5, which gets you to 108.
You can use inverse operations to check the work
108 x 5 = 540

Every point is moved so that it is 1/2 as far
Step-by-step explanation:
This will change the size of the shape and it will no longer be congruent, or of equal size to the original.
Answer:
Every point is moved so that it is 1/2 as far from the x-axis.
Step-by-step explanation:
Let's go down the list:
- Every point is moved to the opposite side of the y-axis but still the same distance from the y-axis.
This is describing a reflection across the y-axis. Reflection is one of the congruence transformations, so therefore, the figure resulting by this transformation will still be congruent to the original.
- Every point is moved 2 units right and 5 units up.
Every point is being moved the same exact distance, so therefore, the figure will remain congruent. This is similar to translation, but all the points are being translated.
- Every point is moved 1 unit to the left
This is similar to the last one, it's just translation, which is also a congruence transformation.
- Every point is moved so that it is 1/2 as far from the x-axis.
This is basically dilation. Dilation is a similarity transformation, but it changes the size of the figure. Therefore, this is the one that will result in a non-congruent figure.

What is the area of a rectangle with vertices (-8, -2), (-3,-2).(-3,-8), and (-8, -B)?
Answers
Answer:
The area of the rectangle would be 20 square units.
Step-by-step explanation:
The distance between the points (-8, -2) and (-3,-2) is 5. This is the length of the rectangle. The distance between (-3,-6) and (-3,-2) is 4. This is the width of the rectangle. To find the area, multiply the length and the width to get the 20 square units as the area.
Answer:
Area = 20
As B = -4
Where -3-1 = -4
We look at x for first measure = -8 -3 = 5
We look at y first sequence change for second measure = -B
x/y = -3-8 /-8 + B
= -3-8 = -8(-8)+B
B = -3+B = -3+1
B= -3+1 = -4
Second measure = -8-4 = 4
Therefore, using both measures in bold : the Area = 4 x 5 = 20
