What is the area of a circle with a radius of 10 feet? (Use 3.14 for ρ.)

62.8 ft 2
78.5 ft 2
314 ft 2
31.4 ft 2

Answers

Answer:

Step-by-step explanation:

The area formula for a circle is: A = pi(r)2

First, you are going to plug in the known measurements... A = 3.14(10)2

Next, you will go step-by=step to solve this.

A = 3.14 * 10 * 2 =

A = 31.4 ft. 2 =

A = 31.4 ft. squared

As you can see, the are of the circle is 31.4 ft 2 and that is also what D. is.

Hope this helps! :)

Benito is selling T-shirts for $8 each for his school fund-raiser. So far, he has sold 16 T-shirts. How many more does he need to sell to reach his goal of $200 in sales?

Three of these equations solve for the number of T-shirts, t, he still needs to sell to reach $200 in sales. Which equation does NOT?

Answers

Answer:

8t +16= 200

Step-by-step explanation:

You didn’t tell us the equations but if it looks like 200= 8t +16, 16+ 8t = 200 or 200= 16+ 8t, it is correct beacuse it is just the same equation but just in a different order.

200\16x8=100 sorry if I’m wrong

A survey of a group of seventh-graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results.

Students

A dot plot titled Students. A number line going from 0 to 9 labeled the number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9.

Teachers

A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9.

Based on the shape of the two-dot plots, which statements correctly compare them? Select three choices.

The center of the data for students has a value less than that of the center of the data for teachers.

The center of the data is to the right of the dot plot for both teachers and students.

There is a greater variation in the data for teachers than for students.

Both sets of data cluster around 2.

The same number of teachers as students were surveyed.

Susie's books take up 0.4 gigabytes of space and her songs take up 9,000 megabytes of space on her computer. How many books and songs does Susie have?

Answers

Answer:

Susie has 1500 songs and 400 books

Step-by-step explanation:

We divide 9,000 MB by 6 MB and get 1500. Susie has 1500 songs.

Then we convert 0.4 GB to MB. If 1000 MB is equal to 1 GB, we have to multiply 0.4 by 1000. We get 400. Susie's books take up 400 MB of space.

We divide 400 by 1 to find out how many books she has. Susie has 400 books.

Mr. Burns built a wooden platform for the Drama Club at the school where he teaches. The shape below represents the dimensions of this wooden platform. (picture is not to scale) What is the surface area, in square feet, of this wooden platform?

Answers

Answer:

108 square feet

Step-by-step explanation:

First you want to break up the "L" into two parts. These parts can be seens as a and b. You need to find out the length on the left hand side, and half of it is 6ft as seen, so if half of it is 6ft, then you need to find the other half, which is obviously 6ft. 6+6=12, and to find the area of the thinner rectangle, multiply 2*24=48. That would be the area of section a. Section b is the bottom section and what you want to do is multiply 10*6 because this is how you would find the area of section b, which would be 60. 60+48=108. I know I was not very descriptive but I still hope this somewhat helps. I also might be wrong because of the fact that it says surface area despite the fact that this shape is 2D.

The surface area, in square feet, of this wooden platform is 84 ft².

What is Surface Area?

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.

We have L figured shape which can break as two rectangle.

So, the Area of rectangle 1:

= l w

= 6 x 2

= 12 square feet

and, Area of rectangle 2:

= l w

= 12 x6

= 72 square feet

Thus, the surface area of figure

= 12 + 72

= 84 square feet

9. Consider the diagram below. First, solve for x, then y.

Answers

Answer:

x = 59

y = 32

Step-by-step explanation:

x + 78 + 43 = 180

x = 59

y + 59 + 89 = 180

y = 32

Answer:

y = 32; x = 59

Step-by-step explanation:

On the top triangle x+y+89=180 because a triangle's angles add up to 180 degrees, while a quadrilateral's angles add up to 360 degrees.

Angle 89 and the angle below it are supplementary, meaning together they equal 180 degrees.

180 - 89 = 91

So the angle below 89 is 81 degrees.

Now we can subtract the other three angles in the quadrilateral to find the fourth:

360 - (78 + 43 + 91) = 148

So the angle below y is 148 degrees.

Angle y and the angle below it are supplementary, meaning together they equal 180 degrees.

y = 180 - 148

y = 32

All of the angles in a triangle equal 180 degrees:

x = 180 - (32 + 89)

x = 59
