what's the area of the circle

Answer:

10 degrees

Step-by-step explanation:

Since a right angle is 90 degrees in total, to find the missing degree subtract 80 from 90.

90-80=10 degrees

Answer:

242.76m^2

Step-by-step explanation:

Given data

Height=18m

Volume=4,374m^3

We know that the expression for the volume of a cylinder is

V=πr^2h

substitute

4374=3.142*r^2*18

4374=56.556*r^2

4374/56.556=r^2

77.339=r^2

r=√77.339

r= 8.79m

But the area of a circle is expressed as

A= πr^2

A=3.142*8.79^2

A=3.142*77.2641

A=242.76m^2

Hence the area of the base is 242.76m^2

Answer:

1) x = 15

Step-by-step explanation:

We use the Pythagorean thm for these questions. Where a and b are the legs (So order doesn't matter), and where c is the hypotenuse

1)

a² + b² = c²

9² + 12² = x²

81 + 144 = x²

x² = 225

You square root each side so you can get rid of the exponent on x.

[tex]\sqrt{x^2} =\sqrt{225}[/tex]

x = 15

6. answer is A.

Answer:

-4,1

Step-by-step explanation:

Y is at -1,1

X is at -5,0

subracting we get -4,1

since it’s rise over run

-4,1

so -4

Answer:

<B is 53.13degrees

Step-by-step explanation:

Find the diagram attached

Given

Opposite side= 4 (side facing <B)

Adjacent side = 3

Required

<B

According to SOH CAH TOAS identity

tan theta = opp/adj

tan<B = 4/3

<B = arctan(4/3)

<B = arctan(1.3333)

<B = 53.13 degrees

Hence the angle <B is 53.13degrees based on the diagram

Step-by-step explanation:

Perimeter of the figure = Perimeter of parallelogram - 14 + Perimeter of semicircle

[tex] = 2(21 + 14) - 14+ \frac{1}{2} \times \pi \: d \\ \\ = 2 \times 35 - 14 + \frac{1}{2} \times 3.14 \times 14 \\ \\ = 70 - 14 + 3.14 \times 7 \\ \\ = 56 + 21.98 \\ \\ = 77.98 \: \\ \\ \approx \: 78 \: in[/tex]

The length of the side AC will be equal to 5.69 cm

A figure consisting of four sides connected together and forming a total angle of 360 degrees is called a quadrilateral.

Given that:-

ABCD is a kite, so AC I DB and DE= EB.

AD = 4 cm BD = 4 cm and CD = 3 cm.

The side AC will be calculated as:-

Since AC is bisecting the line BD so BE = ED and BE = 2 cm and ED = 2 cm. WE have AD = 4 cm so we will calculate AE first by using the Pythagorean theorem.

AE² = AD² - ED²

AE² = 4² - 2²

AE² = 16 - 4 = 12

AE = √12 = 3.46 cm

Similarly, we will find the value of EC.

EC² = 3 ² - 2²

EC² = 9 - 4 = 5

EC = √5 =2.23

WE know that AC = AE + EC

AC = 3.46 + 2.23

AC = 5.69 cm

Therefore the length of the side AC will be equal to 5.69 cm

The total volume of the composite figure is 64 in³.

The volume of a rectangular prism, V = lwh where

Since horizontal rectangular prism has a length of eight inches, a width of two inches, and a height of two inches. So,

So, its volume V' = lwh

= 8 in × 2 in × 2in

= 32in³

Since the vertical rectangular prism connected at the right end of the other prism has a length of two inches, a width of two inches, and a height of eight inches. So,

So, its volume V" = lwh

= 2 in × 2in × 8 in

= 32 in³

The volume of the composite figure V"' = V' + V"

= 32 in³ + 32 in³

= 64 in³

So, the total volume of the composite figure is 64 in³.

V = 105 cubic centemeters

Answer:

It would be 30$.

Step-by-step explanation:

Lets break this down.

50% off 100 would be 50. 50 is half of 100, therefore we know that 50% is half off of something.

We can either divide 60 by 2, or split 60 in half. In turn, we receive 30.
