What formula do we use to find area of a circle?
Group of answer choices

A=πr2

A=3.14d

A=πd

Answers

Answer 1

Answer:

Your answer is A.

Step-by-step explanation:

When finding the area, you multiply π (3.14) and the radius (r). Then, you square the product (x2).

So, it is A = πr2

Hope this helps! :)

Answer 2
A! Pi is obvi 3.14, times the radius times 2! other person probably explained it better but hope this helps!

Answer:

x ≥ -4

Step-by-step explanation:

you subtract 10 on both sides to get x by itself. 6-10 = -4. since you already have x by itself you don’t have to do anymore

Answer:

The answer is x ≥ -4

Step-by-step explanation:

First, subtract 10 from both sides.

x + 10 ≥ 6

 -  10   - 10

Which would make x ≥ -4.

28 out of 50 8th graders said they prefer snow to rain. 42 out of 58 10th graders said they prefer snow. did a larger percentage of 8th graders or 10th graders prefer snow?

explanation please

Answers

A larger percentage of 10th graders preferred snow.

Answer:

10th graders prefered snow then 8th graders did.

Step-by-step explanation:

Hey I hope I will be able to help!

To find out the percentage we need to divide the fractions-

28 divided by 50 = 0.56 and in percentage form its 56%

42 divided by 58 = approximately 0.72 which is 72%

56% < 72%

72% is obviously greater so 10th graders prefer snow more than 8th graders do.

The outline of Sara's family room, including the entry, is shown.

Sara wants to carpet the family room. How many square feet of carpet does she need?

Answers

143, multiply 9 and 12 then you get 108. Then subtract 7 from 12 to get the length of the top square an that is 5 then you multiply 5 and 7 to get 35 you add that to 108 and get 143 hope this helps:)

The number of square feet of carpet Sara needs is 128 square feet.

What is area?

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

From the given figure,

Dimensions of a large rectangle, length is 12 ft and breadth is 9 ft.

Area of the large rectangle = Length×Breadth

= 12×9

= 108 square feet

Dimensions of a smaller rectangle, length is 12-7=5t ft and breadth is 13-9=4 ft.

Area of the smaller rectangle = Length×Breadth

= 5×4

= 20 square feet

Total area = 108+20

= 128 square feet

Therefore, the number of square feet of carpet Sara needs is 128 square feet.

You randomly choose one of the four marbles. Without replacing the first marble, you choose a second marble. there are 1 blue, 1 green, 1 yellow, and 1 red. Use tree diagram

Answers

Answer:

12 total possible outcomes

Step-by-step explanation:

To do this, we can use the Fundamental Counting principle, which is :

An event M has m possible outcomes. An event N has n possible outcomes. The total number of outcomes of event N followed by event N is m x n.

When you first pick up a marble (event M), there are 4 possible outcomes (yellow, red, green, blue). Since you do not replace the marble, when you pick the second time (event N) there are only 3 other possible colors.

As we know, m x n = to total possible outcomes.

So, 4 x 3 = 12 total possible outcomes.

Find the volume of the following figure. 890 units 3 900 units 910 units 3 882 units3​

Answers

Answer: 882 units cubed

Step-by-step explanation:

The following shape is a cuboid, which means we need to multiply the length by height by width.

The units we are using are cubes.

To calculate the 3 dimensions, we need to manually count the cubes.

Length = 14 units

Height = 9 units

Width = 7 units

Volume = Length * Height * Width

V = 14 * 9 * 7

V = 882 units cubed.

Which means, in that big box could fit 882 little cubes as shown.

A right rectangular prism has a length of 2 ½ feet, a width of 3 feet, and a height of 1 ½ feet. Unit cubes with side lengths of ½-foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?

Answers

Answer:

n=90

Step-by-step explanation:

As I think it is easy to answer the volume of prism I will also calculate no of small prism that can fit inside the larger one  

so volume = length * width * height

volume of larger prism

vp=45/4 ft^3 =11.25

volume of small cubes

vs=1/2*1/2*1/2

vs=0.125 ft^3

now numbers of cube that can fit

n=vp/vs

n= 11.25/.125

n=90

so 90 smaller cubes will completely fill in the prism

Answer:

11.25 [tex]ft^3[/tex]

Step-by-step explanation:
