A semi circle is half a full circle. Find the area of the full circle and divide it by 2.

Area of a circle = pi x r ^2

R is half the diameter

Area of full circle:

Area = 22/7 x 21^2

Area = 1386 sq. Ft

Area of stage = 1386/2 = 693 square feet

Answer:

3.14 x 42 x 42 = 5538.96ft

If your wondering why used 3.14 instead of 22/7 is because they are exactly the same just one is a whole number and the other is a fraction. I suggest you use 3.14 because its easier than 22/7.

Answer

number of side(n)=6

formula to calculate each interior angle =((n-2)×180)/n

now,

((6-2)×180)/6

(4×180)/6

720/6

120

may this will help you

Answer:

120°

Step-by-step explanation:

n = 6

Work:

[tex]\frac{(n-2) *180}{n} \\\\\frac{(6-2) *180}{6} \\\\\frac{4 *180}{6} \\\\\frac{720}{6} \\\\120[/tex]

1, 140 °

2, 40°

3, 100 °

4, 100°

5, 40°

6, 90 °

7, 120 °

8, 130 °

Step-by-step explanation:

1, BOA IS EQUAL TO FOH = 140°

2, FOE EQUAL TO BOA = BOA = 40° = FOE = 40°

3, BOA° + GOF° =40° + 60° = 100 °

4, GOE = BOC WHICH MEAN GOE = 100° = BOC = 100°

5, COD = HOG =40 °

6, EOD= AOG = 90°

7, AOD = GOE + COD = 100° + 40 ° = 140°

8, BOG = 140 °

Answer:

A + B + C + D = 52.35

Step-by-step explanation:

Here, we want to get the sum of A, B , C and D

from the question, s represents the number of small candies

L represents the number of large candies

Let us start with the cost;

small candies cost 10 cents; that is same as 10/100 = $0.1

large candies cost 25 cents, that is same as 25/100 = $0.25

so therefore, A is 0.1 and B is 0.25

C and D represents the total number of candies bought and that is 52

So, the sum of A, B , C and D is ;

0.25 + 0.1 + 52 = 52.35

Answer:

P equals 18 because 8 plus 10 is 18.

Step-by-step explanation:

Answer:

a=3

d=19-3=16

recall that:Tn=a+(n-1)d

T100=3+(100-1)16

=3+99×16

=3+1584

=1587

Therefore T100=1587

Answer:

2+3=5(x-4) ,

=5(x-4)

=5x-4

=1x

Answer:

The height is 7 inches

Step-by-step explanation:

Given

[tex]Base\ Area = 15in^2[/tex]

[tex]Volume = 105in^3[/tex]

Required

Determine the height [missing from the question]

The volume of a hexagonal prism is:

[tex]Volume = Base\ Area * Height[/tex]

Make Height the subject

[tex]Height = \frac{Volume}{Base\ Area}[/tex]

[tex]Height = \frac{105in^3}{15in^2}[/tex]

[tex]Height = \frac{105in}{15}[/tex]

[tex]Height = 7in[/tex]

Answer:

Calculating the means:

Sum each length from each sample and divide it by the number of worms.

Sample 1: 26 + 25 + 27 + 19 + 24 + 26 = 147/6 = 24.5

Sample 2: 24 + 23 + 24 + 26 + 25 + 25 = 24.5

They each have the same sample mean.

Ranges: Take the largest length and subtract the smallest.

Sample 1: 27 - 19 = 8

Sample 2: 26 - 23 = 3

Sample 1 has a greater range.

Answer: 13.79%

Step-by-step explanation:

Amount spent on broadcast TV advertisement = $10000

Amount spent on cable TV advertisement = $15000

Amount spent on radio advertisement = $4000

Total amount spent advertisement = $10000 + $15000 + $4000 = $29000

The Percentage of radio advertisement done will be:

= (Amount spent on radio advertisement / Total amount spent advertisement ) × 100

= (4000 / 29000) × 100

= 13.79%

Answer:

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

Answer:

36π cubic inches

Step-by-step explanation:

V = 4/3 πr³

radius (r): 3

= 4/3π(3)³

= 4/3π (27)

= 36π

Answer:

First estimate:

63% is kind of close to 60%

41 is kind of close to 40

its easy to compute 60% of 40 - it's 24

Second estimate:

14% is close to 15%

96 is close to 100

15% of 100 = 15

Answer:

1st one is 25.83, so estimate that so it shud be like 24

D) [tex]8\sqrt{3}[/tex]

Step-by-step explanation:

a² + b² = c²

x² + 8² = 16²

x² + 64 = 256

x² = 192

[tex]\sqrt{x^2} =\sqrt{92} \\x=8\sqrt{3}[/tex]

Answer:

55

Explanation:

Answer:

A is the correct answer. pls mark me brainliest

Step-by-step explanation:

You have this rule, if there is < 30° then value of y is

y=12✓3:2

y=6√3

And Pitagora's theorem:

c²=a²+b²

In this case:

(12√3)²=y²+x²

Then x is:

x²= (12√3)²-y²

x²= (12√3)²-(6√3)²

x²=432- 108

x²= 324

x=✓324

x=18cm
