Three semicircles are placed in a rectangle, as shown below. The length of the rectangle is 72m. Find the area of the shaded region. Use the value 3.14 for pi , and do not round your answer. Be sure to include the correct unit in your answer.

Answers

Step-by-step explanation:

Width of rectangle = 7 cm

because ∵ width of rectangle is equal to the radius of each semicircle.

therefore ∴ radius of each semicircle (r) = 7 cm.

therefore ∴ Diameter of each semicircle = 14 cm

therefore ∴ Length of rectangle = 3 x 14 = 42 cm.

Answer:

63.21cm'2

Please! Mark me as brainliest please.
Your answer is 1049.76

72 divided by 3= 24, 24 is your diameter of each semi circle

To find the area of your semi circles you’ll use pi times radius squared.

Aka 3.14 times 12^2 divided by 2 = 226.08

Times 3 for 3 semi circles

226.08 times 3= 678.24

Now find the area of the rectangle and you get the height from the semi circles which is 24m

72 times 24= 1,728m^2

Now you take the area of the rectangle and subtract the area of the circles

1,728 - 678.24 = 1,049.76m

What is the total height of all the plants?

Answers

Answer: 6 1/8

Step-by-step explanation:

1/8 x 2 = 1/8 x 2/1 = 2/8 = 1/4

1/4 x 3 = 1/4 x 3/1 = 3/4

3/8 x 4 = 3/8 x 4/1 = 12/8 = 1 4/8 = 1 1/2

1/2 x 3 = 1/2 x 3/1 = 3/2 = 1 1/2

5/8 x 1 = 5/8 x 1/1 = 5/8

3/4 x 2 = 3/4 x 2/1 = 6/4 = 1 2/4 = 1 1/2

Start with the big number first.

1 1/2 = 1 4/8

1 1/2 = 1 4/8

1 1/2 = 1 4/8

5/8 =     5/8

3/4 =     6/8

1/4 =      2/8

Add them all up.

1 4/8 + 1 4/8 = 2 8/8 = 3

3 + 1 4/8 = 4 4/8

4 4/8 + 5/8 = 4 9/8 = 5 1/8

5 1/8 + 6/8 = 5 7/8

5 7/8 + 2/8 = 5 9/8 = 6 1/8

From the set {37, 50, 63}, use substitution to determine which value of x makes the inequality true.
[tex]x - 13 > 37[/tex]



A. 50

B. 37

C. 63

D. none of these

Answers

50 - 37 = 37 (doesn’t make the inequality true, since it equals 37)

37 - 13 = 24 (doesn’t make the inequality true since it’s less than 37)

63 - 13 = 50 (this is correct because your answer is greater than 37)

Answer: C
37-13 is less than 37 50-13 is equal too 37 so c is the answer

How do I solve this problem for 7th grade!

Answers

Its 55

35% = 35/100
So 35/100*200 <- 200 is the number of all tags
When you do this, you’ll get 70
So 70 tags are blue

Next, to find how many yellow tags, just
3/8*200 = 75
There’s 75 yellow tags

If you add both amounts (70+75) you’ll get 145

Now we know there are 200 tags and 145 of them are yellow and blue, so the rest are red
200-145 =55

Answer:

55 name tags are red
