Answer: A group of students formed a circle during a game.The circumference of the circle was about 43.96 feet,and the diameter of the circle was 14 feet.Which expression best represents the value of π? The expression which represents the value of π is option C from the attachment that is π = 43.96/14

Step-by-step explanation:

Given:

Circumference of the circle = 43.96 feet

Diameter f the circle = 14 feet

So,

We know that :

Circumference of the circle = or

Re-arranging the formula:

⇒

⇒

⇒

⇒

Plugging the numeric values:

⇒

So the expression for π is 43.96/ 14,and option C is the correct choice.

Please please find the area for this polygon!

Answers

Answer:

508

Step-by-step explanation:

28*16= 448

6*6= 36

4*6= 24

448+36+24= 508

In order to find the area of a polygon, all you have to do is follow the formula: area = 1/2 x perimeter c apothem. To sum it together, perimeter = the sum of the lengths of all the sides. So add 6, 16, 16, 6, 4, 6, 28, and 18! And then you have 100! Then multiply it by 1/2! So your answer should be 50. Please consider brainliest.

The semicircle below has a diameter of 20. Find the area of the blue region.

Answers

Answer:

61

Step-by-step explanation:

Use the area of semicircle minus the area of the triangle. Area of the semicircle is 10^2 * pi / 2 = 50 pi, the area of the triangle is 12*16/ 2 = 96. The the area for the blue part is 50 pi - 96 = 61.07963268 or 61.

If it is helpful, plz give me Brainliest.

Answer:

50pi - 96

Step-by-step explanation:

The radius of the semicircle is 10, so the area of the entire semicircle is 1.2*10^2 pi = 50pi

The white triangle has an area of 1/2*12*16 = 96 so subtracting it shows that the blue area is 50pi-96

Answer:

65°

Step-by-step explanation:

the angle of a straight line has to add up to 180°

if it doesn't, it's not a straight line

115° and x are supplementary angles

meaning we know they have to add up to 180°

so simply subtract

180- 115 =

65°

you can check work by adding

115+65= 180

Answer: 65

180-115=65

Step-by-step explanation:

A straight line is always 180 so I subtracted 115 from 180.

B $??? $14

C $60 $???

D $??? $59

Answers

Answer:

See missing answers bold

$20 original = $5 final paid           as $15 was s/p before -10 was added

$30 original = $14 final price        as $24 was s/p before -10 was added

$60 original = $35  final price    as $45 was s/p before -10 was added

$92 original  = $69 final price       as $59  was s/p before -10 was added  

Step-by-step explanation:

Ans in bold  

A) = f(x) = 20(0.75) -10 =  15 - 10  = $5                 = £5 final paid

B)= f(x)  30 (0.75) = 24 - 10 = 14                           = $30 original price

C)  = f(x) = 60(0.75) -10 = 45 -10 = $35               = $35 final price

D)     = f(x) = 92 (75) = 69 -10 = $59                    = $92 original price
