Step-by-step explanation:

A=2πrh+2πr^2

=2×22/7×3×6+2×22/7×3^2

=113.14+56.57

=169.71 m^2

Step-by-step explanation:

r = 3 cm

h = 6 cm

= 2 × 3.14 × 3² + 6 (2 × 3.14 × 3)

= 56.52 + 113.04

= 169.56 cm²

Answer:

a= 180-60-55=65

we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a.

b=180-90-65=25

the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b.  

c=25

c is 25, because two angles on both sides of a X is the same

Answer:

3960.4 bacteria

Step-by-step explanation:

The formula to solve the above question is given as:

P(t) = Po (2) ^t/k

P(t) = Population after time t = ?

Po = Initial population = 650 bacteria

t = Time in days = 7.3 days

k = doubling time = 2.8 days

P(t) = 650 × (2)^7.3/2.8

P(t) = 650 × 2^2.6071428571

P(t) = 650 × 6.0929582599

P(t) = 3960.4228689 bacteria.

Approximately = 3960.4 bacteria

Therefore, the number of bacteria the researcher will have after 7.3 days if they started with 650 bacteria is 3960.4 bacteria.

Answer:

The answer is 94.5

Step-by-step:

This is actually quite simple. Although, in order to do this you will need a calculator. First, you identify which trigonomic function you will use in order to find the value of x. for this problem you need to use the COS function. The equation for this is COS67= 67/x. Because you are trying to find x you would multiply each side by x. now the equation is xCOS67= 67. because you still can't find the value of x by doing this you will need to get x by itself. To get x by itself divide each side by COS67. the equation is now x= 94/ COS67. This is where the calculator comes in. On the calculator enter 94 divided by 67 then COS function. This gives you the measure of RS.

Answer:

I would choose two 12 inch pizza if I want more pizza as two 12 inch pizzas have larger circumference than one 18 inch pizza

c=πd

circumference= pie × diameter

c=2πr

circumference= 2×pie×radius

A=πr²

Area= pie×square radius

Pie= 22/7, 3.14( depends on the question, sometimes the value of pie will be given in the question)

radius= half of diameter

To find perimeter of circle use 2πr

To find area of circle use πr² or πd

Answer: 4.5 days or 4 1/2 days

Step-by-step explanation: We can use cross product property, to solve this. Workers to Days remember that  

If 8 workers can build a wall in 12 days. How many days will it take 3 workers to build the same wall ?

In this question we are provided that 8 workers can finish a piece of work in 12 days. We are asked to calculate how many days it will take 3 workers to complete the same work.

We can solve this question using two methods :

[tex] \small \green{ \underline{ \underline{\bf{ Unitary \: Method}}}}[/tex]

8 workers can build a wall in 12 days

1 worker can build a wall in 12 × 8 days

3 workers can build a wall in [tex]\dfrac{12 × 8}{3}[/tex] = 32 days.

[tex] \rule{47mm}{4pt}[/tex]

[tex] \small \orange{ \underline{ \underline{\bf{ Method \: of \: proportion }}}}[/tex]

Let us assume that 3 workers can build a wall in x days.

[tex] \begin{array}{ cc } \bf{Number \: of \: workers} & \bf{Number \: of \: days} \\ 8 &12 \\ 3&x \end{array}[/tex]

Ratio of workers = Inverse ratio of days

[tex] \small\sf{ 8 : 3 :: x : 12}[/tex]

Product of mean = Product of extreme

[tex] \rightarrow \small\rm{ 3 \times x = 8 \times 12}[/tex]

[tex] \rightarrow{x \: }\small\sf{ = \dfrac{8 \times 12}{3} = 32 \: days } [/tex]

[tex] \rule{73mm}{5pt}[/tex]

Answer:

x = 15

Step-by-step explanation:

(10)(18) = 12x

x = 15

Answer:

X=55° Y=35°

Step-by-step explanation:

X+Y=90°

Y= x-20

(X-20)+X=90°

2X-20=90°

2X=110°

X=55°

55°+Y=90°

Y=35°

Answer: opposite/hypotenuse

Step-by-step explanation:

Answer: $221.76

Step-by-step explanation:

Each wall has a length of 12 and a height of 8 and there are 4 walls

(12 x 8) x 4 = 384 sq ft

multiply sq ft by cost ($0.33)

384 x 0.33 = $126.72 for the walls and door

The ceiling has a length of 12 and a width of 12

12 x 12 = 144 sq ft

multiply sq ft by cost ($0.66)

144 x 0.66 = 95.04

add the costs

126.72 + 95.04 = $221.76 total

image of drawing of room

Answer:

A

Step-by-step explanation:

Step 1, Identify the coordinates of each vertices in the pre image

A ( -2 , 3 )

B ( 1 , 3 )

C ( 3 , -6 )

D ( -4 . -6 )

Step 2 apply dilation.

To apply the dilation we multiply the x and y values by the scale factor. ( assuming that the dilation is about the origin. )

The scale factor is 2 so we multiply the x and y values of the coordinates by 2, which is as simple as it sounds.

A ( -2 , 3 ) -------> A' ( -4 , 6 )

B ( 1 , 3 ) --------> B' ( 2 , 6 )

C ( 3 , -6 ) ---------> C' ( 6 , -12 )

D ( -4 , -6 ) ----------> D' ( -8 , -12 )

Hence the new coordinates are A' ( -4, 6 ), B' ( 2 , 6 ), C' ( 6 , -12 ), D' ( -8 , -12) Which corresponds with answer choice A

Answer:

27 feet

Step-by-step explanation:

Total distance from base of lamp to tip of shadow

15 + 8 = 23

-------------------------

tan∅ = opp/adj

opp will be the height of the lamp

adj is 23

--------------------------

tan 50 = opp/23

multiply both sides by 23

23 * tan50 = opp

Use calculator

27.4 = opp

Answer:

116.25 ft²

Step-by-step explanation:

Height = 7.5ft

Perimeter : 2(7.5)ft + 2x ft = 46ft

Length = x ft

15+2x = 46ft

31 ft = 2x ft

x = 15.5 ft

7.5 x 15.5 = 116.25 ft²
